I remember seeing this quite lovely fanart just a week ago. Sadly, I cannot find it again.
It was a female!alphonse. Long hair, cute little skirt and top outfit. I wanted to show it to someone, and cannot find it again. Any help would be greatly appreciated.
And to make this post a little more worthwhile, I have a few screencaps from the image gallery on the Conqueror of Shambala DVD. Please don't hotlink, but feel free to take them.
