Low Polys - difficult.... I think so

So I'm making progress on the cartoon head, it's looking a little more refined. I'm also learning how to use Milkshape to add and remove faces at will. So far, the head only has 138 polys. I could probably go lower, but I think I may go a bit higher so I can smooth some parts out, plus going lower requires a LOT more experimentation and tweaking than what I ever imagined.
