Nice solid map-making here - the layout is good, there's a bit of detailing even, which could be enhanced though IMHO.
What about adding some sound entities, I bet wind would be great for deepening the immersion into the maps ambience!
And a lot of maps have that crackly sound placed near the torches, which always feels more-or-less right (beware the volume!).
The only real gripe I have TBH - those jumppads .. that texture .. weird.

A little bug I found:

I like finding maps on here I originally saw on coopedits. Having said that there was one part that I suggested in the coopedit that you changed back. You have two pillars on each end of each bridge, and at the part where they join it's just a flat box and the edges stick out. That's not a huge deal but it looks awkward. Maybe you can remedy this with a metal box texture at the part where they join, and incorporate some metal texturing into the map to make it more interesting (for now you really only use 2-3 textures).

Same thing with the staircases beside the pillars, they don't seam perfectly and there's bits sticking out. I know it's hard to fix..

The layout's pretty good though. It looks like a skilled jumper will be able to make fantastic use of it. My only suggestion would be to put the quad where the healthboost currently is, and move the healthboost to where the shells are on that one platform. Basically they should be harder to reach than they are, and not so close to each other. The healthboost right now is harder to get than the quad which doesn't make sense.

Good map though. It's not great as the textures are limited and the theme is somewhat basic but it's good.

Also: the packaging should be fixed. You have it as folder>packages>map>map file. It should be folder>packages>base>map file. Also there should be a screenshot in there. The screenshot you used is bad; use /hidehud 1 to get rid of the hud in the screenshot.

how can i change this node ??

Well, I'm not saying ditch the theme you already have established, but maybe incorporate a metal theme into it.

I like the map, if you need any tips from an Icelander, just let me know ;)

This map isn't too bad really, despite the crappy packaging. The map has nice flow in most areas, some good jumps and a quite like the theme although it's nothing exciting.

of course there are a few areas that need work on in the map.
The weapons placement and supply is poor and there are a very small amount of weapons for 5-8 players, realistically this map is suited to 1-4.

The quad is too accessible and should be moved to where the two rockets are (don't put two rockets next to each other either..)
If you look at some of the most popular ffa maps you will see there are usually at least two of the weapons except for nades. I would add a few more rifle and mg rounds and move the rocket rounds to better spots.

I also feel some of the jump pads are a little too easy particularly the one on the back wall where the GA is. Just reducing these a small amount could make the map nicer and a little more engaging to play.

There is also one area I find rather annoying, which is the tower between the quad and the rockets. I don't think it shouldn't be there as you need a route between those points, but it is too big and the edges of it make it awkward.

Other than these points I think you've made a good effort on the map and should try and fix these things up so that the map can have good game play in all modes. 3/5
