the dirt helps but it seems somehow put there without sense... i mean like if u took the uvmap into ps and slapped a few brush strokes. NOT THAT IT LOOKS BAD... but it will look better in places where it could b justified, like close to the thruster or in the edges where dust gets accumulated... anyways this is coming along nicely.
kinda reminds me of a distorded game boy Good work. I love 3d Art. It's such a challenge to make; you have to have TONS of patience. Good job on teaching yourself how to texture. A good model isn't worth anything if it's just a flat, dull texture.
