Why does the throwing look so fucking odd?
The spear points left one shot, right the next, and left-center the last. Eyes naturally follow directed objects spears (think arrows ->); it's hard to settle on this shot because you keep getting impulses to look different directions when you expect to be following the smooth parabolic of an object in flight.
It's the same reason GAF looks like garbage; people got avatars facing left all over the place, screwing up consistency. You try to read the page left-to-right, top-to-bottom, every once in a while an avatar catches your eye that draws attention from the posts on the right onto the avatar itself, and to the left off the screen.
