Animated Animals

I've always found animals amazing things, but I've never been able to draw them particularly well, this is something I've been trying to improve recently. I'm trying to intertwine what I'm learning about the moving human figure and implement it with animals, to make them look more animated.

When drawing an animal I will always try to find a picture of the animals skeleton online to study, I always find it useful to get an understanding of the underlying structure and how it all fits together first.
