I have a few in mind, like tribal meshes and stuff, but I'll only request one... I know it must really take time to make a single mesh, so. :x
Hmm, would a skull of some sort, like a feline or cat skull be too complicated? Doesn't have to be perfect.
Also, about the tutorial you mentioned, I think that'd be amazing actually. Very useful, since I don't think I can find very good tutorials about this stuff. Maybe there are some, but my brain doesn't work when I read through them, apparently...
