Oh god, vectoring. I'm taking the grand meander through every single art process and tool.
Actually, sounds like it could be a lot of help, and I had no idea it was something that could be done in Photoshop (I thought it was an Inkscape thing). I was looking around for a tool that'd do something similar, but Photoshop's incomprehensible interface was absolutely no help. Thanks for pointing that out, I'll take a look at it tomorrow!
