Well, as the description implies I'm mostly being silly, but that shading doesn't resemble shading much at all. It looks most like the torso and knee, but curves up too much towards the side of the legs, plus seems to have its own shadow. The shading in general goes a bit quirky there (e.g. both the light from above and that from the lava misses the top of that leg entirely even though both go much higher up the foreground leg), so I guess it was just an awkward area. I mean,she wasn't trying to include an anatomically correct cartoon horse on a MLP cover.Still, I thought it'd be fun to giggle at the outcome.
