The squirrelis a bit big and the legs are just a little too short. Also, The anatomy of the leg isn't quite right.

I added a bit to the image to show your leg anatomy and what I use as a structure

Hope this helps!

thank you, he's short and stubby HAHHAA

Like nuts. showed I like to start with drawing circles in the points where key body parts and joints would be and then I end up connecting the lines and then tweaking here and there. I also think you have a good start to yours paws as they are a pretty simplistic body part to begin with all you gotta do is make it 3D which when you get the joint stuff down is super easy ^~^
