thats a very nicely done iso for first time :) keep it up! 

cool            

Lol great scene. I have played on this map many times and you have reflected it nicely :)

I myself saw the blurry and sharp texture combination very compatible, floors that looks like "dirty tools" is just a simple texture of 6 colours and I did not make that by accident.

Here's your orange guy: [link] just to compare.

 I think you could improve the main surface by making it less blurry.  Looks like dirty tools were used.  Not saying they were, just that it looks that way.

Everything else is pretty good.  I like the dimensions, the orange guy, and the weapon spawns (Quake 3 was the last FPS I ever played).

 Nice work here. The colors are nice, and it's fairly readable. Good going!

 Not too shabby for a first go
