i like the face... especially the nose and the lips area look good.
i guess u are heading into a manga-style character. if so, i would exaggerate the body proportions a little bit. or else it looks like a manga head stitched on a real body.
i also think that u could scale the head a lil' bit down. i know anime chars have big heads, but i think it would look better when the head is smaller.

keep up the good work.

cheers
