Hello!  I'm making a mobile game that is an endless runner, and although I have a sprite designed, I am having a hard time having the animation flow smoothly.  I need a running, rolling, and sword swinging animation.  Also, if you would happen to have any revisions that you could recommend to make the sprite better, please add those as well!  Here's the first frame of what's supposed to be the running sprite for the character (yes, it's supposed to be a koala):

Edit: Just realized I can't even figure out how to put an image in sorry about that!  Email me if you would like to see it!
