uhg I like how you colored it , I like the shadows from the hair strands but the hair looks as black as the mountains in the background :
I turned up the brightness on my computer's monitor up to maximum (100) to be able to see the strands and the contrast too : but my eyes got blinged by the strong colors on this page when I did that :
I suggest you raise the brightness a bit and then the contrast too so the hair won't loose the contrast between the lighter strands and the dark part.
overall the image is quite nice :P
I really love this. It's amazing. The ONLY thing that I wish you would of done though was to make the shine a little brighter. I know that would probably be hard with all the strands but I think it's one of those things that is very noticeable in Hinata. I am no critic though and like I said, I really do love Hinata and this piece of art.
