As an abstract composition, your image is superb - the modified "L-" shape of the stairs and railing is echoed by the similar "L"-shape of the water. The reflections in the water and the mischievous boy, perfectly placed, add tension and a dynamic feeling to the composition.
Cute picture! The clarity, lighting, coloring and everything else looks great! I like the reflections in the water... that child is making me nervous... be careful :) :) ~Rachel~
