I gave you a pretty low rating and the reason for that is that I personally don´t see how this ties in with the challenge theme as I don´t see anything even resembling a bubble in the whole photo and I looked carefully. On top of that I don´t find the photo flattering at all as I strongly dislike blown out highlights and lens flare. Just wanted to explain why I gave it a 2.
Please don't be offended by this comment. I am making an effort to comment on all images that I scored below a 4. Although your image meets the challenge requirements, I believe attention to the following might have served to make it work better for me (Mind you, this is only MY opinion):
I like the idea of a parasail as a bubble. However the darkness, contrails and sunflare are a bit overwhelming.
