Nice use of color
I just love the use of color in this one and you presented some good "SHADING" also like the color with hair eyes and eyebrows, that was kind of a nifty idea, also great job on using the whole canvas allthough some of the backround you could have used, and one last point that may or may not help but ill throw it in there anyways maybe some extra shading on the skin tone for the extra detail but doesnt seem like it needs it, anyhow its a great portrait. anyways keep up the decent art works.
~~THINGS TO IMPROVE ON~~
some extra shading on the skin tone and maybe a touch of backround in the bland backround spots.
