I used "hidehud 1", just screenshot text are invisible in game, but visible in screenshot, i dont now why=)

Press "F12" next time instead of using the console line. If that bind doesn't exist (yet), put the next line in your autoexec before starting up Sauerbraten:
bind "F12" ["screenshot"]

Now about the maps;
Package it into a "zip-file" instead, as it's one of the lines of the packaging-requirements on quadropolis (.rar used to be a trouble for mac-users).

The first map (scdm1), lacks or has been done oddly in the following things:
- Geometry, as you tried to create some kind of wall but it's not logical in it's existence at all. It's just an ugly square-shaped wall with some ground textures on the surface.
- Texturing, as the wall should carry a way more fitting texture. Also, using alpha material on a floor texture isn't a smart idea when it doesn't have a purpose.
- Light-sources, as some green light gets emitted out of nowhere. There isn't any explanation why the green light is existing.
- Clipping/noclipping. It doesn't have any sense at all, like you can't jump over the fences. There is some ammo putted behind it but somehow you really need to take that door which ends in a noclipped wall to grab the ammunition, very odd.
- Positioning entities, as they are just putted randomly. Ever heard of the command "entselsnap"? It's binded as shortkey by default on the "6" when your in edit-mode.
- Only 5 playerstarts in the entire map which are most of the time facing each other, really? Be sure to add at least 8 of them and don't let them face each other like it currently is.

Up to the next map (scdm2), which lacks more as the previous one:
- The geometry isn't great at all, it's just even more square.
- The texture is insanely bad, as only 3 textures has been used. Be sure to use at least an amount like 30 textures.
I won't go tell what's wrong about this map, as it's not worth my time actually. It just looks like a map which has been made in less than a minute.

And the last map (scdm3), which has a similar quality as the first map,
- Again, the map is way to square. The shapes of surfaces aren't matching, but "fighting" against each other instead. There are also a lot of geometry-errors in the pool. Don't use several gridsizes when you don't know what your doing.
- This map has some more textures, but not they aren't fitting their surfaces at all. Don't use a light-texture to cover up huge ceilings!
- You seems to have learned this time to learn about light-sources, but your still not able to create a certain atmosphere (which is 1 toughest jobs for mappers).
- Ever heard of adding velocity to teledests? It can be done by adding a "1" in the 3th slot of a teledest (like this "teledest 0 180 1"). It prevents camping on spawn-places a bit and increases the flow.
- Woohoo, you've added 7 playerstarts! Still a very small amount compared to the size of the map, so add like 12 playerstarts at least.

These are just a few points which could be improved.
I consider those maps as experimental maps, which shouldn't be posted on quadropolis. Go map some more, learn the basics at least and then reveal the result of some real map.
I won't give it anything higher than just 1 point at the moment.

P.S.
It's not the meaning around here to create a content (or merge contents) just because you've improved a particular map. Keep avoiding this to avoid clutter.

Okay, i will add power to teleports, i really did'nt know about this option =)

//I love low-poly maps, couse im lover of Quake I -II (Most Quake I) map style =)

Well, maybe you've checked out one of my maps (like scedm5 or evilness), but I also like the "Quakish" style. Why? Because artists of Quake based maps particular on flow and gameplay mainly, which puts geometry, texturing, lighting and detail on the second priority, but still IS a priority. That means they haven't abandoned those points, but started creating a good flow and gameplay first, then create good geometry, texture, add lighting and detail the map.
This is what your still lacking, while the gameplay and flow aren't that great at all. That's why I recommend to first go map some more, finish maps (which you won't put on quadropolis as they only have a slight better quality as these maps) and after your sure a map you just made has some solid quality, then post it.
It's not a bad thing to observe included maps like ot, turbine, metl2, metl3, metl4, complex, etc. You could learn a lot from those maps as some have different styles of gameplay and flow.

Your maps are good, but based on quake III style =) (Curves) But it have some qI (Like strong rods at the seling)

Well, the problem is that Sauerbraten doesn't have such gameplay neither such flow as Quake (any of the series actually).
It only has slight comparable things which are trickjumping, teleports, jumppads (even tough they work very different), Singleplayer and the weapons.
Like:
- The rocketlauncher is similar to the one in Quake3Arena.
- The grenadelauncher is pretty unique in rate and power, but the idea is probably from any of the Quake series.
- The rifle for hitting opponents from a great distance, is very similar to the railgun of Quake2 and Quake3Arena, but you can't shoot trough several opponents with just 1 shot.
- The shotgun is very similar to that of any of the Quake series, exept its rate of fire.
- The machinegun for hitting targets which aren't far away, but not close either, as could be seen similar to the lighting- or plasma-gun.
- A weapon which uses infinite melee like a chainsaw, which is very similar to the gauntlet of Quake3Arena)
- Another weapon which players recieve when spawning by default, which is in the case of Sauerbraten a pistol. It depends which version of Quake, but the Quake2 pistol comes the most close to that, even Sauerbraten's pistol isn't having infinite ammo like one on Quake2 has,
Sauerbraten is one of the few games which support trickjumping on all weapons (except the chainsaw, but it previously had some recoil).
The movement and gameplay is way different, as all versions of Quake have some sort of strafe-jumping and Sauerbraten has just an accelaration jump like Unreal Tournament, even it's just limited to accelerate just once.
- Unlike any of the Quake series, Sauerbraten lacks sounds like footsteps, spawning, a sound so you can hear your opponent took a powerup like the Quad or Healthboost (like Quake3Arena has), etc.
It also seems to be a sport to include maps which are as open as possible, unlike Quake maps are.
Those things are actually just a few points which makes Sauerbraten similar or different to any of the Quake series...
