If you were going for a simplistic piece, this is perfect, but if not, here are some tips! The eyes should have pupils or darker ovals inside, and try to add a bit more color into it. The hair could use some texture, so you could add some lines in there... And the piece is a little too on the warm color side. In a piece, it's always best to have balance. If there is too much of a warmer accent, the image no matter how clear it is in reality, will appear to be too soft or blurry to the mind. This illusion problem can be troubleshooted if the outlines are smaller and don't differ in color from the rest too much. If the skin is light peach, for example, and the outlines are brownish, then the image will or look feel too hot, like the sun is shining too bright. If cool colors such as aqua and light blue are utilized, then it will give the impression that the sky or some water is also there to counterbalance the effect of the warmer colors. Also try to use colors that are closer to being in the middle, such as purple and green, as these colors alone are more balanced than the rest, being in between the warmer colors and the cooler colors, or at least close that. The neck in the lower area should be clear and distinct until the shirt appears, eventually being cut off by the edge. Most portraits do this to keep it realistic. The hat could also use some texture as well, and that should be all.

Also, it wouldn't hurt to add a design to the hat.

^^ I hope this helped!
