Cute idea :-) Really like the concept. And it comes off well too. I like the different colors and how you've placed them from warm to cool starting in the center. The shadows look good and the lighting is very nice. Really good crisp focus too, very clear. Well done!
I really like the whimsy of your image. The angle of the sun in the shadows really add to the photo. I can tell you thought this out very carefully and set it up in order to achieve this effect. Congratulations on a job well done.
