The last 2 look pretty difficult to model, given that I can't figure out sculpting yet, I'll probably HAVE to as all my weapon models need normal maps, though I could paint bumps and generate fake normals.

I don't really think the two-handers are very in tune with the extant warhammers either (this is what is in the game so far http://www.uesp.net/wiki/File:OB-it.....Warhammers.jpg they are more hammer shaped)
Might be fine though.

what else
EYES, EVERYWHERE.
