I had to get that out of my system, because quite frankly it's the reason I made this. I'm sorry, that's the way it is.
Taking four screenshots I sewed them together to create the full picture of Ed. Using another shot from that scene (Episode 20 of Fullmetal Alchemist: Brotherhood) I kept in the rain theme and the hues. I did recolour part of Ed but if I'd have tried to tackle the water and such on him I'd have made more of a hash then it already is.
