Gah only now do I realize that it was quite rude of me to just ask that without commenting on the flash.
I think it could use a little work, the foot doesn't even make any contact with the other character. Its kind of funny, but I'm not a fan of "symbol" animation. Try out drawing each frame out (reusing existing animation when applicable.)
This is not Blockland related, nor does it have a point at all, but it does demonstrate what I mean. I Made a series of 12 frame walk cycles in a symbol and then just dragged it across the scene.
Enjoy.
