Wow, a very nice shot. I love the color in the balloon, and how the back lighting just adds to the contrast in the balloon. I might have cropped it closer on the balloon since the green countryside is not all that interesting, and it would have removed the vignette from the lens while drawing more focus to the subject. Were you in another balloon or something else to get that great perspective looking down?
Too bad the second balloon would not get his shadow out of your shot! Great perspective getting the shot from above and the fields are a perfect back drop. 7
I think the only thing that is a problem with this is it may be a touch too bright. I tried some quick adjustments to it, and it really took the visual pop up this shot up a notch for me.
