Nice color palette. The lighter sky definitely says "light" more than your other options, although your earlier character design with the centaur body and bow had some great pastel hues that screamed "light side" more than this does.
I think the latest pose is not as strong as the one before it. The new silhouette is not as dynamic or interesting, nor easy to read. The hand and gun just blend into the body, making them harder to parse.
Great rendering progress overall, though, and good luck whichever you choose!
