Yes the Walk uperbody and legs movement look off.
-The hand doesnt moevs along with the leg well.
-The belt barely moves then sudenly at the last frames jumps foward that dont look good.
l-ooks weird how the elbow moves like it moves aroun 1 pixel more than it sould be could try to make is forearm moves too.
Probably would give you a better result if you just use áll K´s sprites for the walk and add the shading of Rouga instead of the Frakesprite imo so is legs could move well along with the uperbody.
