He kinda looks like he's suffering from an allergic reaction to medication? A bit on the "puffy" side; but maybe you're gonna fix that in the detailing?
Perhaps he just ate a peanut that didn't agree with him?

Also, I keep expecting to see that occipital bump at the base of the skull, just a touch at least.
And I also have to agree with the lip comment that Joopson made.

Other than that, pretty superiffic.
