jealousy

Nice moment. There isn't too much to critique here save technical/composition since everything else is out of your control.

That line dividing the jealous onlooker and giraffe is on the golden section... so far so good. You've given the jealous giraffe some space, which is good.

That bar on the bottom right clutters the image, though, as does the stuff in the top left corner. By using Photoshop, you can remove these distracting elements and simplify. (The alternative is to crop, but that would most likely hurt the composition.)

Regarding one minor technical aspect, the eye of the jealous giraffe on the right seems a bit unsharp/blurry. Photoshop would help here too, without compromising the DOF effect on the brick wall by making your aperture smaller.

If you need any clarification on my critique, just ask!
