An amazing creature! Just truly!
A couple things I would like to point out right away is the face and whiskers. It seems a bit "rushed". I know you may not be feeling well, but this is quite good! The whiskers need less colored pencil. I love the fluffy design! And the blue is a perfect choice to bring out its "pure white" qualities. The body may be a bit too long. But that depends on what you are looking for. The long body gives it a unique "graceful" appearance. The hind claws seem to be a bit uneven, as if they are blunt. The hind leg closest to us is probably the most obvious. Try to make the claws touch the ground. The shading on them is otherwise perfect!
I love this a lot, and hope to see more!
