nice pose, maybe try to work on the paw´s for the next sketch,

well he, i just can say it again , please get some white paper somewhere your art´s would look much better without these lines ...

and when you have scanned them try to adjust the Gamma , and contrast (with ,Microsoft Photo Editor, or something like that , i do the same with my pencil sketches before i upload them..... that´s all for the advice and critic by now LOL

Weell...this was taken on a phone not a scanner (I dont have one). And his paws look like that because in Dr. Seuss books nobody ever really has hands.
