Here's what it looks so far.
What are your motivations for making said sprite? I am sure there must be a zillion of him out in the interwebz. If you want to do something original for him, I would say make some animation sprites for him. In positions and actions that aren't normally done. Such as a running sprite, or battle stances and attacks.
Sorry, I Just can't find any sprites of him that I like, so I just decided to make one.
That's cool! Well good luck, I hope it turns out good for you.
