Nice shots, the fencing in the foreground adds to the shot of the leopard in my opinion as it tells a story of captivity and goes with the slightly nervous expression in his face (one reason why zoos always leave me feeling a bit depressed
The shot of the panda is nicely composed, but it looks to me to have a bit of a green cast to it. Easily sorted in an image editor though. Good work!
