Focus appears to be off a bit and the lighting is pretty harsh with everyone in their own shadow. The levitating fellow on the left looks a little strange.
It just doesn't say "bummer" to me... *sorry* It says "Summer Fun" without the title, and I think it should say 'bummer' without needing an explanation in the title.
Not for me, its just beginning yaay! Nicely captured action, composition and cropping. Lots to look at, and the washed out colours really do give it that end of summer feel - soft sun, long shadows, slight breeze.
