Sorry, went off to play Far Cry 4.
I'll probably be making it up from scratch so that the softening won't be a problem. Are the ink drip lines up above looking good enough?
I'm probably going to do all of this in photoshop, honestly. Vectors in Illustrator are a bit too much work. Ink lines I'll be doing using my tablet, because pressure sensitivity and drawing by hand makes things smoother, easier, and faster. For the hard lines I'll probably just have those as vector shapes and then have duplicates for the vertical bars that I'll rasterize and blur, then play with the opacity to get the faint glow from the original.
