wasnt meant to be, I ant make shapes like that & ive been the most unsuccessfull bloke ever at making computers & stuff.
Theres a bit in my competition map where ive put a grate in the wall, Thats because all my attempts at making a computer screen were utter shat.

The first 3 are really cool, but the big red texture seems perhaps too sharp? Some sections of it end too abruptly (noteabley the red fixing things, which have an odd looking white border) and the pipes look an entirely different style to the rest of the piece. Good work though, you improve at things at quite an insane rate my friend 
Yeah, wut ReNo said Some of the edges need softening a bit, and cleaning up a little. Theres still a fair bit of white on that last one that i'm guessing is the remnants of the previous background. A 'lil bit of lassooing (spelling? ) should do the trick.
The first texture would be nice if you made the black background masked (that nice blue colour) as I can see it working really well with a glowing panel behind it.
I wish I could do proper textures but i'm kinda limited in skill to cartooney style stuff.

Some of it looks rendered even. There are spots of "dodgy edges", most notably in the last texture. Anyway, like ReNo said, it's great to watch your skills develop.
