I've been working on this for about a month, off and on. It started with the foreground guy's eye and worked its way outwards, with no clear direction known. I have no idea what it's supposed to be about beyond the obvious subject matter, but for some reason it has held my interest long enough to get this far. It's now at the point where I could tweak it indefinitely, but would be unlikely to improve it significantly and would probably introduce regressions. I'll let it marinate a while. I'm thinking of using it as the basis for my first larger etching.
