I'm back.
I don't think that it's the chopping off the head that bothers so much as much as the fact that there is lots of room on the left and right that calls attention to that and makes it seem like a mistake.
That graceful hand in the lower right is terrific.
You have a nicely symmetrical face, great eyes and cheekbones and excellent chin.
If you have any flaw in your face at all (and its a minor one) is that your upper lip isn't quite as full as the lower. A smile or a slight outpouting of the upper lip might be an attractive route to try.
