Run spike run

Oh my gosh this picture is pretty cute of Spike in his dog form.

The realism here is amazing despite it being a animated cartoon. It looks very professional and true to the name, suits it's theme.

Lets see here. The first thing that comes to my mind is the lovely pose you have Spike the dog in. It says a lot about him and the overall tone of the art piece. You've got some good form on the body and your canine anatomy is flawless,

I also really like the lighting here. I like how Spike's fur is shaded. It all looks pretty well done and adds depth to him.

The background isn't too much to look at. It's simplistic enough to add to the art piece, but not too distracting to draw away from the center of the piece. Spike. The grass is also a nice addition.

Overall this is a very interesting piece. I absolutely love your style.
