I generally agree with probo
but also the general pose of the clone is a bit too weird and unrecognizable, at first I thought it was some kind of arching lightning that got stuck in that position for some reason. Even when you guess it's a character the pose is not very humanoid, someone hanging from their hips is just not likely to do that spiderlike pose, The shading style of the clone is also really weird and very unlike the original sprite OR STF, I wager if they made an energy being in STF he'd be more sillouethy and clear. The whole thing is a bit confusing, didnt strike me as a clone of himself at all.
so my advice for it, have the clone animate more, have him do a more complete take. have him go out, get to a more recognizably human pose, go a bit further than that and snap back, show him moving like a human being, not just sorta blur into the final pose. Also, tweak the energy clone to be more in-style and sillouethy
