I added the curtain on the right, but I wanted them to be transparent but couldn't remember how do to it, so I ghosted an image of paris over them, rendering Gilbert out. Then I added a more solid image of Paris in the background (same one just different levels of opacity). Dropped on a few textures, fiddled with the lighting, color, etc.
I chose lyrics from When I'm Gone by Three Doors Down, because the country of Prussia ceased to exist around 1946 or so. So I have the letters of the words fading to reinforce the fact that Prussia no longer exists. ((thank god Hetalia is a comedy, cuz no one wants to see Prussia literally fade away))
Oh. And this is fanart, hope you don't mind.
