It looks like you had fun.
In the first, it looks like the ring is the subject, but it's hard to see because it's so small. I think it would help to have a much closer crop. Also, it would be nice if the ring had been in the light and not in the shadows. Maybe try lightening the hand and darkening her face?
The 2nd looks like it could have used some fill light. You caught a great expression though.
