I finally was able to get to a scanner to post a page of sketches. :b Anyways, hopefully this will give you some ideas on what I was talking about. Though your recent work shows impressive improvement. You're really getting into your style!
To help with anatomy,have you tried drawing the sceleton of the animal before fleshing it out? Just a wireframe, then put shapes on it, then put the detail and erase the frame and shapes. If you want, I can post a tutorial in my scrap folder. (I might do that, anyway for a friend..)
