Thanks D-jinn. You are right about the transition between idle and runing states. This is mainly because I made the animations separately, then joined them in one file, thus they look different and it feels abrupt when the anim changes between them. I will add some interlude frames.

Great animation, I like it, but there's an issue with the walking animation, just there when the anim changes from stand-walk and walk-stand, maybe you need to put some frames that makes an interlude from both animations, because it looks strange when she starts or finishes walking.
