Yea. The part where the wing has a nail at the top is often considered to be a hand, because apart from the thumb with the nail it has multiple (in this case 4) long fingers. In this case the index finger seems to have an additional hand at the distal end, which has 3 fingers.
Technically as a reply to you both, I think those are the clawed tips of the character's wings. If you look, you can compare the wing tips to the 'claws' in the water, and they look like the same thing.
