I'm not sure what kind of critique you would want. Since the only medium you are using here is pencil I'm only going to focus on that. A thing that would help this drawing more is darker lines and erasing the lines that don't contribute to the piece. Adding tuffs of fur to the joints also can help give it the illusion of fluffy fur without going crazy on the details.
