Ahaha, the first one made me laugh. Looks like the Wild Wolf from the 3 Little Pigs.

Mind if I C+C?
In the first one, the glasses seem too bent...maybe you could curve the glass up a bit more?
The second one is really cool, I like the colours.The tail seems to have lost its life and seems like a ball of cotton, though...maybe you could shade it to look more like fur?
Not much to critique on the last one (looks really neat, I like the spots!), just that it seems a bit too dark, especially where the arm crosses over the tail.
Other than those minor things, I like 'em
