Playful Midnight

First critique so I'm sorry if I sound silly or I'm not helpful >.<.
What can I say about this piece. It's adorable, the eyes just make me melt into a pile of goo and make me want to rub the eevee's tummy. There are a few things I'm going to note however. Shading wise you have it good on the body, but your light source is a bit off. Of course we all shade differently. When drawing something think about the creases and where a shadow would appear on them. For instance, from my perspective the hind limb on the left could use shading between the crease between the thigh and the rest of the limb. If that makes any sense. Also the chest fur could use a bit more shading and highlights to make it pop. His proportions are a bit off, especially the forelimb on the left. I must agree with the tongue, some shading around it and highlights would really make it appear more three-dimensional. Other than that you have a very cute piece here. I hope this was even a little bit helpful ^^.
