I really like the pose you used for your sculpture; the claw idea really works in Views 4, 5, and 7. However, I think in order to make your hand sculpture resemble its real life counterpart, some more work has to be done on the fingers and palm shape. If you make each joint section in each finger more distinct (right now it mostly looks like one large curve, such as in View 8), clean up the lines you etched into the skin of the fingers, and build out the palm in profile (such as in View 8), those details would make your claw idea stand out even more.
