I like this, but not the panda so much. For one, pandas are cool, but everyone already knows this. There are a lot of interesting animals, but everyone wants to go for the panda... this is more of a personal issue though.
Technique wise, I also thing the panda is of worse quality. He has that weird line on his chest, and his face looks very mousey. So much so I'm not sure he's a panda... which bothers me because your fox looks most definately like a fox and it seems inconsistent to be so stylized with one but not the other. Also, he looks like he's going to fall over... no one can stand like that, despite stylized perspectives. And I think the lightest shade of AA on his leg is too light.
Also, the upper left blue region of the circle could have it's AA improved.
But this is very good. I like the fox very much. As for the hand, I feel like a more bonier or clawlike hand would fit better than mickey mouse and bugs bunny hands.
