From what I'm seeing, the texture is a skin from Minecraft. Ergo, it might be possible to import your Minecraft skin into Unity, and using this model as its base.Highly promising.
Great model, but I don't particularly like the wings. The hand claws also look broken.Would had like to see this model with dynamic bones (especially the tail).
This model's viewpoint is wrong (due to the head bone being shorter than the actual head of the model). And the arms look broken.I don't recommend this if you want a realistic model.
