Skull Logo (WIP)

[Masna]

Trying to get some AA practice.  I've never really done anything like this before, so C+C would be greatly welcome. 



EDIT: Some folks over at Pixeljoint helped me make some tweaks.


EDIT 2: Possible final rendition?

[EyeCraft]

Mainly a colour edit. Make sure you get maximum use out of your values for stuff like this.

You had your values like this:
0,  19,  50,  100

This limits where they can be used and what combinations they can be placed in, you're better off with this:
0,  33,  66,  100.

Main thing to avoid is creating any banding.  The top of the eye is a particularly prominent case.
