heyas; i dont know if you could actually 'over do' the face.... you could try sizing up your current texture to 3000x, leave the face and re-do the skin. you might also look into re-mapping the figure to use separate texture maps for the body and the head. all you need to do, really, is assign the head's skin material to a new name, and you should be good to go. then you can apply your 1200x texture to the head (and it's component parts), and the 3000x texture to the body (and it's component parts) ;)
