Why Can't I Be a Homunclus

FMA and SDK crossover. K, after massive computer problems, I'm finally done. It probably lack some details (ie, Homunclus symbols), and some shadings are quite odd, but I think it turned out good. Supposely for (sorry for the extended time) Halloween contest. Just in case if you dont recognize who's who. From the left, Saizo as Envy, Yukimura as lust, Kyo as Roy (wow, even the name is similar), Yuya as Ed, Benitora as Huges(indeed I have problems drawing both of them..) and Sasuke as Riza. (Also disregard the height chart, I really dont know how tall they are)
