The glasses look great in panels 2+3! Now, I bow to your superior artistic knowledge (I can barely scribble, and don't even properly understand the theory behind scribbling!), but would it look more realistic if the lines didn't quite match up? I mean, if you look at another person's eyes through their glasses, there's a little shift so the lines behind the glass don't quite line up with the lines unobscured by the lens. Or would that just be distracting in this medium?
