Make the eyes bigger and more Glowy, More shades of QS/Platinum, and It looks good so far. And DONT clutter, You're making it good, keep it up.
unsymmetrical please. Make different textures for left/right biceps, But still make them mix into the adjacent textures. Also, add more more abstract designs to it.
Can you make the Left hand like a grandient?
A dark point (Almost black) at the center of the fist, then slide out (Brightening the colour) into smooth flames.
And have them over lapping onto the wrist(Just a little bit).
And do whatever you want on the right hand.
my advice:
bigger eyes, bolder. slight glow, not that fade out like you mentioned. screws around with the tribal theme.
so ya, bigger + slight glow
