NIce to have the bubbles blown into the picture - good off center. I like the reflection of the trees in the bubbles. Wisht the background were either sharp , or better, really out of focus so the bubbles would show up better.
turn to the left/ step right.. allowing the green grass to be the only backdrop, or further shorten the dof .. but I think just the green grass with this would be great. nice clarity, and I really like the reflection in the bubble.
Doesn't look off-center because the bubbles are at least half of the subject. It's a GREAT shot however, but just doesn't fit the challenge that well. :(
Hmmm, I recognise this theme from somewhere (person blowing bubbles)...!
Think you needed a less cluttered background. There's too much going on in the picture, it's hard to know where to focus. Other than that, nice! Perhaps some more bubbles as well? 6
