I'll just piece it together randomly from that sheet if I can't figure out what each individual section is. I want the authenticity that comes from using official textures. It can automatically make something look a lot better (like with pico).
It will be hard, but far from impossible.
If I made my own texture, it would look fine but it wouldn't look nearly as good as this sheet. I can texture pretty well on Samus because everything lines up pretty easy. Sheik's random straps of cloth is what ruined the Zebesian texture from the very beginning.
After looking at it a few times, it is laid out kinda logically at least.
Everything between the "face" at the bottom and "pincer" at the top is all chest texture. The grey part there is the bottom part of the left shoulder.
The tear shaped bubbly grey thing is the tall parts of the shoulders.
I just found this nice little render from MP2 that should help with laying some of it out. I think this model will look pretty close to it once I get the texture on there.
