Ooh, I see what you mean, those white spaces above is annoying. Hate to see that awesome Winry Rockbell signature like that ><. Too bad I don't know the solution.
BTW, I just wanna mention that the Enma Ai picture that Umi used is also the same one used in last yr. Amethyst 2010. Umi submitted 2 Enma Ai poster (the 2nd one is better, IMO), so KS could probably substitute the 2nd one in as her entry.
