Im trying something kind of similar to that with a squirrel. What i've done so far is skinned it from the waist up to its head (turned out not bad) and i've soaked in some hot water for a little bit. So now i think im going to salt the inside down....insert a wire through the head and front feet so that they're in the position i want....stuff it with something...and put some eyes in. haha, yeah, im kind of winging it since i've never done anything near to this before so wish me luck.

PS. your mount isn't half bad one on one
