Because the fic is so dark and hurty I wanted to make sure the art had the proper tone. The scene that stood out to me for that was Dean when he's sitting in the Impala [fic spoilers]outside of the abortion clinic, imagining what could have happened if things were different.
I drew this all on a black background, which is not as easy as it sounds. But Batman: The Animated Series painted on dark backgrounds to get their atmosphere, and it really does work much better than just painting in the black around everything.
I ended up with a nice movie poster feel to it, IMO, and am very happy. Big, huge, massive thanks both to mashimero for reference pics and for dimeliora for being one hell of a harsh taskmaster and refusing to let me fuck off in the final hours of this.
