Everything near the hoof-thingy' glow has very strong lines on the edges, and the far lines are very faded and blurry. I overdid it a little because the character has very smooth skin, but even with fur and whatnot, you can get a similar effect by making it more irregular.
edit: other picture was a super page stretch.
