I like how you've composed the elements here, especially how the hand is small and based at the bottom center. However, it's an action of "letting go", not a "feeling" as the contest specified. Oh well. Still a pleasant photo. :)
To emphasis the challenge it might have been better without the house in the background. The trees help to show the height of the ballons well enough. Also if the hand were a bit less centered it might be stronger.
I did this same shot as one of my two possibilities for this challenge. I wish I would have had your blue skies! Nice photo, but I wish the house wasn't in the picture. I think it would have been better with a simple background. Focus and exposure are good.
This was one of the ideas I thought of and chose not to enter. In retorspect, I think that was a mistake. This is a happy image with good colors. The focus is a little off, and the curvature effect of the tall trees doesn't help this, but, overall, a nice effort.
