Realism
@evulnater: It's called perspective, and I think it has been uniformly over-applied in an artistic way.
It's strange to look at this image, because I associate the darker line-drawing feel (most noticable on the toes, ear, mouth, and eyes) with your typical over-the-top accentuation of details as in a cartoon. Here, though, all the shading and proportions are subtle and realistic, with no hyperbolic emphasis on anything. It is a representation of reality, but through the lens of your hyper-real artistic style.
I like it and think it is a fantastic drawing, but it's jarring all the same.
