Also not a big fan of the head. Reminded me of Coneheads, and that movie scared me. So, I did an 8 minute paintover to show what I envisioned his head like, don't get mad.

I chopped off the top, gave him an island (islands are -awesome-), pulled the nostrils in just a little, eyes down and in a tad, as well as a smidge smaller, and took the liberty of giving him a last name and a love of ricecakes.
Also, the eyes look like they kinda angle up in the middle ^, but that could just be the angle of the shot.
Sorry if I butchered it, but that's what I envisioned it like when I first saw it...
