I agree about the chunky leg: my logic was it might not be noticable, and if I did a good job on the texture it should be good enough. In the side view the thickness should be about right.
Anyway, as with all my models, I try to be extremely economical with polys, and the leg was just one of those choices. Looking back, I probably made the wrong choice - with the forearm I will use 2 bones with a 'real' gap between them. I realise in the big scheme of things 1000 polys isn't too bad, but my end goal is always a game of some kind, and for a low level monster, 1000 polys seems like a bit much (since it is reasonable to have 10 skeletons on the screen, depending on the game).
