I think more even lighting would make for a better shot; esp in the second shot, you have more light on the knuckles than the ring itself, it's a bit distracting. Hope my crits are constructiveCongrats!!
The blur looks too fake in the first shot. Look at the tips of the fingers. At least it was distracting for me.
Second shot is awesome. Makes you look like a big spender.
Congrats dude.
