Human form. ^__^
And Phoenix_Kensai, there are also some FE fanart on deviantArt, but you have to sift through redrawn pictures of the original art to find the good ones. ;P
EDIT: Okay, maybe I'll link to some good ones. Sanaki, Lucius, Stefan and Soren, Edward and Leonardo in Lucky Star style, Saleh, Stefan, just to name a few.
