First of all, never EVER EVER work on lined paper! It absolutely
kills a drawing!
gonk The ware-wolf certainly seems fearsome. Kudos for being able to get an animal muzzle down properly-- that's farther than I ever get. However, I think it may be more effective if its face were narrower-- 'round' tends to translate as 'cute' to a viewer's eye, and that is certainly NOT a mindset one wants about a bloodthirsty creature.
I like how you defined the fur-- it is very flowing, and the bristles show the body language well. May I suggest that you add some more shading to it? Maybe it's just because of the camera, but it seems like there's an overhaul of middletones. Think about where the light would be coming from and what the light is (maybe an eerie full moon casting a soft glow onto him?), and add your darks and lights accordingly. I've found that fur looks absolutely
gorgeous when shaded properly in pencil.
As for its anatomy... the leg that's farthest from us seems to start a bit too high up at the joint, and its arm seems a little too long for its body.
Not much to critique on the second one-- the expressions on the jester's masks were done superbly.
3nodding As for the third... DEFINITELY study up on human anatomy. Her torso is very, very smushed. The nipples should be two head sizes down from the top of the head, navel/elbows three, crotch/wrists four, partway through the upper leg five, partway through the lower leg six, bottoms of the feet at seven. This can be manipulated once you are better at proportions to express the character's personality better (such as smaller is cuter, longer arms/legs makes one look silly, longer everything makes them look graceful).
I hope that helped.
3nodding If you want to look more into anatomy and have MSN, I can send you a wonderful book on figure drawing that helped me a million.
