(Historical Notes: Okay, this one ALMOST works.  If It’d bothered to put an extra layer of brightness on the very middle of Trigger and Alphonse’s art, the slight bleeding through of the rest of the background wouldn’t be too bad.  Most of the background image is light enough to bot obscure the line art, the color scheme fits the sailor suit design of the charters, and light reflecting onto another surface honestly looks a lot like the surface of the water itself just showing through.  It’s just that dark, shadowy patch showing through that messes everything up.  Dang it.)
