Nice shot! I like the balloons and the slide, and the whole Park atmosphere. Her outfit is really good for this kind of shot too. Maybe it would have been cool if it focused on one or two of the bubbles a bit clearer. But I don't know how you could do that since they're constantly in motion. Just get lucky I guess.

It's a little busy in the background, like with the fence and the trees. Oh...haha....and it it does kinda focus on her cleavage a bit more than it needs to. It's the darkest spot on the picture after all. She's making an awesome face though, and your lighting is really good.

Hmm....and one last suggestion maybe... everything seems to swoop off the picture to the right a bit. The bubbles, her hair, the balloons, the angle of her arm, even her eyebrows. Maybe next time something interesting to try would be having a strong visual element that brought the eye back to the center or the focus of the picture. I don't know, I'm just throwing out ideas.

Nice job, and keep taking pictures!
