I like this overall as I think the balloon tops are interesting and your POV is unique. The one thing I'm not crazy about is the bg being a dirty yellow. Probably not a choice for you, but it is what it is, eh? Best of luck to you in the challenge.

Wow. very interesting. Looks like you are up above the ballons. The color of the sky is a bit off putting. I know sunsets and such bring interesting colors but one sort of expects the usual blue and can get thrown off but yellow I guess. The clarity in this is astounding though. Nicely done.
