Hi
I'm working on making an action RPG game and I really want the graphics to be as great as I can make them. So far I've made some grass tiles, and one of the main characters.
Tiles:

Character:

As you can see I have started working on a run animation for this character. That is one thing I am particularly unsure about and would really like help with. Should I add more frames? Is it bad how much her leg kicks forward (and how can I fix it)?
I have a semi-animated version of the sprite here for anyone that has a gif program handy to look at it: (unfortunately all I have for animation is Game Maker and the very clumsy UnFREEz).

(The image only animates once.)
All sorts of comments are appreciated but what I'm really looking for is edits and criticism to help me improve the graphics and the graphical style of the game. Things I'm especially concerned about are the run animation and making the girl's head and face look right. I plan to post all the graphics I do for the game here, until I'm satisfied that I know what I'm doing.

Thanks for looking!
