So I restarted that Musashi head...

I'm not good at this painting stuff >_>. It takes me so long to do.

Using Yasuo from LoL as a color reference. Will likely change the tones of the colors just a bit, but not too much.

Edit: Could you folks give me some tips for the nose? I've done some experimenting but still can't get one that looks nice on the sphere (Should I add a shadow for the nose?).

Also, really like the contrast on the Darth Maul head. This is a small suggestion, but maybe consider moving the pupils away from the center of the iris in the direction of the nose? If you put them directly in the middle of the iris, then the pupils aren't focusing on anything and it looks like they're staring off into infinity which is kinda strange. The stretching of the sphere can exaggerate this effect too (Only really noticable on giant anime eyes though).
