Cool work with the textures. I am a bit of a failure with Photoshop so pointers are definately welcome. I also totally agree that the shell should be darker, when I saw it in gane, especially high res, I was kind of disapointed.
Also, the shell is like a 10 sided polygon because you guys said to keep it low poly, but I could always up it to 15 for the high resolution one (I forget, is lod0 or lod1 high res.?)
Here's the texture I'm using, I posted a png (photobucket doesn't let you do tga) format; however, obviously, I use dds for the texture in game - DX5 and 13 mipmaps, and I use tga when I'm not saving in PSD. I also have various pieces and versions of the shell still in PSD format. The general progession is PSD --> TGA --> DDS.

As far as stuff I've done, I've just either done colors or used images from google. Then, I did film grain, rough strokes and some other Photoshop filters on different parts of the texture.
Thanks guys.
