It looks great however I agree with the others. You need to fix the claws, add some muscle definition, fix the shadowing, blur the raptor a bit, work on the floating, and work with the textures. Something that wasn't mentioned that would make a huge difference, would be to use darker colors. The raptor is far too bright, that takes away from the realism. The eyes could have a little more gloss too. But hey it's looking great, just keep at it.
