This was taken at the zoo with of course the glass in between...not to mention the few dozens of people crowding the attraction.

All I have done so far is trim the original photo to focus on this handsome fella, but other than that nothing.

I HATE the way his belly almost blends with the background, so if there are any suggestions on that or anything in general they would be appreciated.
