On a Pauline Baynes theme, the right hand bird-man reminded me of the illustration of Tash from The Last Battle. Not so many arms, obviously, but the pose and claws...
Oddly enough, I was looking at that very illustration today (while trying to find the minotaur one - I'd mentally amalgamated two from the Aslan-killing chapter of TLTW&TW)! I hadn't made the llink, but I loved that picture as a child, and it was almost certainly playing on the subconscious.
Where are your animal heads from, out of interest?
They're just a mix of odds and ends that I've picked up over the past couple of years (mainly from the local games store). One is a skaven head (from a period, apparently, when the skaven looked very little like rats). One is a GW tyranid. The bird-men have GW gnoblar heads. And the two big wolves are GW Hobbit wargs.
