Here is a texture test for my Mecha Shark entry for the contest:
I am not sure I like the base colour. I am more interested in what you all think of the rust colours that I have here so far. Do they look OK? Any advice or crits would be appreciated.
The texture was painted by me in Photoshop, (with a damned mouse - what a pain), and also did the bump a specular maps as well.
While you’re painting the textures, you may want to consider throwing in some sea-like corrosion, i.e. greens and blues. Looks like you’re definitely on the right track though.
