Hi everyone, this is my first post here! I've been drawing for years but am new to pixel art. I've recently started helping with art on a game my husband and our friend have been working on for some time now (http://www.tanaronline.com/ if you want to check it out).  It's a 2-D MMORPG type game with top-down perspective. The sprites were originally done by DoLL, and he has given me permission to edit them. I've already made changes to the shading and tweaked the animation some. Now I have reached a point where I think it could be better, but I'm not quite sure how, so I'm asking you all for help!

Here's the walking animation (done in GraphicsGale):

Thanks for the reply! It only has 4 frames going each way, they wanted it that way so it would be easier to make armors etc. (not having to redraw as much) but maybe it would be better with 6-8 frames.
Off to go study tutorials and the animation books I checked out from the library! :)
