Technical (Comp, lighting, color, focus):
I can see you've got a good dof on this; focus looks nice and sharp; as mentioned below it seems as if these zebras need their legs. Sometimes you can get by with cutting off legs, but this is a case where they need them; perhaps because of where you cut them off....right at their bodies.
Challenge:
Yep!yep! no DNMC here; you got it!
Artistic/Emotion:
This is a nice straight forward piece of work. The blue in this adds to the artistic feel.
Emotionally there's not much there.
Summary:
Great focus, beautiful dof, nice choice for a negative image. The thing that I see that would most improve this shot the most? Show a little leg ;-)
A couple of zebras in this challenge - such a logical choice. They're black and white regardless of which way you shoot them! Very sweet image with the baby. Wonderful that he's staring straight at you. It's also rather interesting that they're such different colors. Was one in the sun or something?
