I think the bow-shooting one is a bit off because her elbow doesn't come far back enough - it seems kinda short to be pulling a bowstring...? Maybe it should also be raised, toward her head?
That last walk cycle's smooth as butter, though, so GW on that one.
It seems like her legs are "shortening" as opposed to bending (the feet don't seem to change perspective; it just looks like you're moving the foot up the shin).
The lighting could be a bit more consistent and direct, as well; it seems a bit diffused at the moment. Lowering the color count and upping the lighting might help to make the shapes and clothing patterns a little more defined, I think.
Anyway, nice work, overall! I like how detailed it is; reminds me of the sprites that came with the RPG Maker tools. Nice spriting work on the hair, as well.
