Eh.. I like the neon feel, but the font your using just kills it :( Try out some different fonts perhaps? Lol and good luck if you plan on doing a car.. those take FOREVER and are hard as hell -.-
erm.. it's not a photomanip lol ;p I like it, got a great feel to the whole piece with the lighting and fog you added. Looks like a desolate construction site to me :) Terragen is always fun to work with, easy to make great pieces with limited time
5image is down for me too :x http://www.imgshare.us/ is a good one, never seen it down, and they pride themselves on having short urls. 2 meg limit, and they support .swf :)
the program's name is cinema 4d lol - Not bad, have you tried adding materials for texture? I really can't help you out a load myself, more of an abstract person too :$
love the originality, not just a boring ice barrage/guy in ice cube sig :) Good shading for the most part, only part i'd consider changing is the sky perhaps? gj anyways :)
