I'm not sure about this, but er... Why did you use diagonal frames for the side walking frames?
Those frames on that specific template, Breeze, were designed to be used for Isometric use (x), not to be thrown into standard 4-way (+) movement.
Anyway, they are quite good, I think a little flat looking - maybe a bit more contrast?
I still really don't like the face you've used the isometric walking frames on the same spritesheet as normal ones.
