Okay, those are pretty cool, but..
- I don't see many people who lift both legs in a banana-split position when they run.
- Looks like you made a new sprite at every frame.. i usually just copy-paste my old one and tweak. The hair and face width look really messed up in the third frames.
I suggest you look through a few tutorials about pixel art (and shading and color theory) before making an entire game. And also, making a game is incredibly hard. Or are you looking for one of those cheapish game-making programs? Yeah, you could use those too.. (i hate them)
Anyways, the greatest pixel tuts in pixel history:
