...interesting layout. Could indeed be fun to play in 1vs1, so much about the gameplay.
I agree with Xsaii about the clip: In some parts, you did a good job using clip, other parts have too much of it. Seems that the rocks you made got broken up when you applied the clip material, try using the same grid size next time (press 7 in edit mode to see the gridsizes).
Some parts are too small to jump, the ceiling needs to be high enough to provide enough space to move and jump (apart from small "sneaking paths", if that was intended).
I also agree about the windows and the crates...you could simply make some by yourself, using metal-like textures.
I like to see the jumppad mapmodels though, that way you simply notice them at once. Lighting is ok for a first (?) map.
The edges you made were a good idea too, it adds detail to the map and looks a bit more "professional".
And yes, these textures have been used very often already, but while speaking of them, the egyptian ones have been overused too, it's just the fact that there are not enough texture sets in sauer which fit perfectly together, maybe make a "look-through" after hitting F2 (or was it F3 ?), to see which other textures would fit together. If you find good fitting ones, you probably get higher ratings, and the map itself will look even better and more "original". ;)
And don't be discouraged by our ratings, 2/5 indeed is "quite good" already :D
So, 2/5, keep it up !
