I had considered Blackheart for Bloodhawk but could not find a reasonably priced one (and used my last one years ago.) Not sure what I was looking for when I come up with using the Bat Creature but felt he was a good base as well. I flipped feet forward to give him toes and removed his wings. I used wings from a How to Train Your Dragon dragon, Hookfang I think, and added them to the base. Re-sculpted his mouth, filled in around the base of the wings, and gave him pants.
