I think the fact that the less cartoonish looking face makes you feel it lacks something tells you what you are after. And just to be clear: it doesn't mean no one would be interested in it. It's just that for instance, I'd not be, and a few others expressed the same above too. Beyond that, it's totally your creation, of course, and your art. If you offer it as a strict morph, it's really not a biggie.
