First impressions are that the Giraffe is lost in all those lines.
Technically this is ok. Composition is good and I'm a fan of shots where the subject is only a small part of the frame. I agree with some voters that the hue is quite unnatural. The lighting looks like it was in full sun - hence the monotone?
Artistically I like the small in frame concept. I'd like to have the Giraffe's head not in the hole as the Giraffe looks a little awkward like he is. Given the advanced editing rules I'd have cloned a couple of distractions from the fence that seem to be attention grabbers.
I had to look at the comments on this one to see what people thought, and I agree. It's one of those shots that would be right at home in Nat'l Geo, or a fine art mag.
