The idea is good but if you move you camera a bit down then the bubbles would be more promiment...presently te hand obstructs the view of the bubbles being forced out
Very nice use of light, highlights the young child's face very well, there's a nice warm glow/tone to the skin. I like the technique of the focus used here, shallow depth so the background blends.. but... I think due to the nature of the challenge, the bubbles should be the items in focus, not the child. Or they should both be in focus. I think its a lovely image, the technique is excellent, I just think from a compositional aspect the bubbles should be precedent or at least have equal play (focus-wise) as the child. Still, a darling image that brings to mind childhood and its fun. I gave a 6.
