That was my idea, you just read in my mind!:) I like the conversion, but in my opinion it woul be better without trunk, there aren't any bones in elaphant's trunk you know. Or is it a kind of armour? May I ask you from wich company have you bought the elephant skeleton? I must know it, because I also want to convert one, to a bone giant, standing on it's two legs and punching flying enemies with it's tusks.
I like the leopard pattern shield too. It looks like not a real but a cartoon panther-skin, but it's OK here.
