Try to make a four fingered hand perhaps with longer digits and tipped with claws. The intelligent species I described in the plans for my role playing game still had long talons but not as long as their cousins the raptors. If not, then just use the five fingered hand of the poser dude and do the claws and longer digits. I agree that three fingers would make it difficult for posing, so four might work better. If too hard to model then go with the five. So while evolving, the raptor picked up a couple more digits. I also gave mine a shorter snout and with a couple of back molars. Though they still were meat eaters, they also could handle vegitation (though farmers weren't held is in as high an esteem as hungers).
