From now on I will rate textures as follows:

Style: 9/10
Mostly for the head

Technique: 2/10
Nothing special

General appeal: 8/10
I love the head. I don't give a damn if they are just brushes.

Next time: try adding shading to the tribals edges to make them pop out. Perhaps grading the colors too. And more then just 1 tribal color. Perhaps red and yellow instead of just yellow. See?

Good luck! Your pricing is ok
