I went into this drawing not really knowing what I was going to do. Basically I started sketching and ended up with this pose, which is Twilight looking all smug and ready for battle, because she knows she can beat you in a magic duel. Just try it.
Anyway, more shading practice here. I’ve gotten a lot more comfortable with the technique, although I still struggled a bit to determine how much to shade where for some of the trickier parts of the pose. The really funny thing about my shading thus far is, I went out and bought that tin of all the different pencils so I could have a full set of B pencils and have ended still just using my HB for 95% of stuff (2H when I just need a touch of shading).
I agree that the lighting is hard to figure out. I would pit Twilight against Fluttershy’s “stare master”.
