This map still needs a lot of work.
The theme of the map isnt orignal, its just another space map...
The lighting isnt great. Lightsources are missing (as in the "boxtunnel"). At some lightsources, the lights only are pointing on the lightsource itself but nothing more (wich lacks realism either). Try to use different colours of lights too.
The texturing isnt that nice too. Some plate-texture has been used as floortexture, the boxtexture in the "boxtunnel" isnt fitting the geometry. This could be fixed by making a cfg for the map wich sets the textures right...
The geometry of the map isnt bad, but not that great. Im fine with mirroring because its a ctf map, but try to add some details so it doesnt really look mirrored (wich gives a more natural feeling).
Try to add trimmings around edges or floors (take as example mbt10, pgdm, dune, park, etc)
The geometry outside the map (and so out of sight of the players) can be deleted. This reduces the wtr of the map a bit...
There isnt much detailing at all. The only detail i could find was some broken part, wich doesnt looks really broken (far too straight geometry).
Clipping/Noclipping can also be done better. Players are able to get out of the map by doing a simple grenadejump (your even possible to get up the walls of the map, by using 4 riflejumps).
The flow isnt right either. There are many dead ends in the map and you bounce against ceilings (like the ceiling with a glass window above it, just above the stairs in the middle of the map.
The gameplay isnt fine too. You only have 2 paths to reach the enemies side (wich are both at the upper floor. I dont count the way to the quaddamage because compared those those other 2 ways, its very time consuming). Try to add jumppads at those holes in the floors, so dead ends get cleared and more paths will exist.
Overall, this map isnt that great. It still has many things to improve. Next time, try to post the map when its like 70% finished, instead of 40%...
Ill give 3/10 for it...
