Wolf Contractor Pixel Animation - Iteration 1

I am making progress with this new pixel animation of my wolf spirit contractor. Still working on out the moves and adding more detail to make the animation more fluid. What I have done are three moves:

Idle Animation, Running Animation, and a Special Punch Animation.

The are designed for more of a 2D side-scrolling or 2D platformer game type. Let me know in the comments what you think about the animations and if you have suggestions on what moves you think should be include: as a reference for that the wolf contractor is primarily a Hand to Hand combat specialist mixed with martial arts so keep to those guild lines if you are making a suggestion. Thank you.
