Nice picture you got here and I enjoyed the information you shared about your character! I think changing the colors around would help a lot; there's a lot of colors, especially on her face, that aren't even noticable. Pretty much the peach, the lines, and that's it. Some more contrast between the colors will help a lot!

thx for that super helpful for some reson if was dodging part of my shading fix it now

It looks like most of the colors are actually transparacies.. I don't know how they got there though. maybe accidental dodge tool or brush tool usage?

I am photoshop C2 so can't check the colour count . If you are worry about me use any random generator tool I havent used them on this picture. So it a little werid for me that you say that I have use 522 colour? is it coz I am using a verson of photoshop that is out of date?

522 colors! That's too many to be accepted at Pixel Joint sadly.

yeah beret are to shade so I have problems with that. with my anti-aliasing what is best way to go about that? do you also think that her neck is little think?

Your outline is good but you need to work on your color selection, shading, and anti-aliasing. For example, you have a lot of hard to distiguish dark grays in her hat. Your colors are very washed out, try experimenting with your palette a bit to find more interesting combinations. Also, its easy to see you mirrored her eyes because you did not corect the specular highlight (white blob).

Hope this quick critique is helpful
