Those are pretty cute.
whee heart One thing I noticed... I'm finding it hard to tell the difference between the male and females, especially in that big group shot. Their bodies all look the same... I'm not sure if that was what you were going for, but I think it'd look a lot nicer if you gave the females a bit more of a curvey shape. Much wider hips would definitely help.
The legs could also use a bit of work. Once again I'm not sure if you intended them to be like... humans in animal fur, or more just upright animals. But right now their legs are straight lines without any real form.
If you're leaning more towards animal-like legs...

Notice how the upper part of the leg is quite wider, and there's a bend below. You could try transferring the same idea to an upright position. Actually, if you saw the most-recent Harry Potter movie (I think it was the last one, anyway...) where Lupin transforms into a werewolf, you can see a good example of how a mammal's legs would look standing upright.
If you want more human-like legs...


(Sorry for the lack of better pictures. XD)
Something your pictures are definitely lacking are
knees. Also, the shape of the legs is pretty much non-existant.
sweatdrop The upper part of the legs is the widest, then the leg narrows at the knee. Below the knee is the calf (that long protruding muscle at the back of the lower leg), which your figures also lack.
So either way, work on those legs!
