The lower part of the "S" should move upwards with the teeth and you may want to add a lower jaw, like EpicWes did.
Also, I don't like the red shade on the light blue part of the paintbrush.
The left side of the head ball thing could be smoothened, there are some bumps where you used a one pixel - two pixels - one pixel pattern and vice-versa.
