I like this, especially the ears!
May I please make a small critique?

Sure what is it.

If you ink a picture with pure black, and then color in the black markings of the character with pure black, then the viewer won't be able to see the details. This is because the line art and the colors are the exact same. So, it's best to go with a very, very dark grey for the markings that are supposed to be black. This is a good example of what I mean, because the character here is a skunk: http://www.furaffinity.net/view/12748685/

That's pretty much what I do anyway.

Oh, alright.
