Lovely artwork I must say, very nice indeed
I can see your constructing the bodies using firstly primative shapes, but you may find it helps to before that consider the space used, Ie where the character and all of their parts are in a 3D perspective then drawing simple three dimensional shapes (cylenders Spheres etc) relative to their position and then considering if and/or how they interact with one another. then doing the details last of all. (you allready knew that bit) you may also do this for the face where the character has a snout, beek muzzel or anything more than the standard human sphere and jawline based head, like in the case of these lovely felines
(I sound so pretencious when I talk all arty thankfully my spellling reveals otherwise)
once again, very nice indeed

I hope I can earn your Critiqe in turn
