Space the final frontier

I have been making progress on assets for my space game and learning how to use Photoshop to do basic textures for 3d models. so i can make my sprites for my game idea. these are the assets so far. what iv been doing is making 3d models of the assets texturing them in Photoshop in the 3d texture mode. then opening the texture file in 2d mode to clean it up before appliing the texture to the asset in 3dsmax to render the asset for the game.
