Testing some stuff out, with angles, and silhouettes, blah, blah, blah so I went with a subject the brain can auto-pilot on. Sharpies on crap paper bleed a lot, and it probably needs another page or two for resolution, but I found it helpful and got what I needed out of it, so probably won't ever actually finish it.
(I also blame this all on rim for absolutely no reason, just because that's what I always do. But really, if he didn't want this, he wouldn't have made Xero so much fun to play with.)
