Greetings from the Critique club. First things first, did you meet the challenge? I think so you have bubbles in the photograph, however your focus point seems to be on the girl not the bubbles. I would have preffered a tack sharp bubble with a reflection of the girl coming through it. As it is most of the focus is on the girl, even though its soft focus, I'd also suggest that you straighten out the background, the wrinkles are very distracting and take away the viewers attention from the intended subject. I do like the composition and I think you had a fantastic vision and I feel that with some of the tweaks to it I mentioned you have a fantastic shot on your hands.
The composition is good and I like how the theme of the bubbles is carried through with the pearls. The wrinkles in the backdrop are pretty ugly though.
