So I was listening to the video above (Say No To This/Room Where It Happens mashup, IT'S AMAZING) when I found this comment:

So because I love AUs and also my bi ass really just wants to draw Maria in a flapper dress, I drew Maria.

(OK, that second reason wasn't the strongest BUT STILL. Also, historically accurate flapper)

Used a luminosity layer for the black and white parts and a blur frame.
