I agree with Craig, I love the minimalism. I like the relationship between the two balloons, but experiment with some cropping, and see if you can islolate the two balloons more.
Hey Jenny, there are 2 ballions in your sky :)
I really like the photo. So glad you uploaded it. Reminds me a bit of an old Czech children TV series. And I agree with Michael, you may try to crop it a bit to put the green one a bit more in focus.
