Taking a look at the latest button comic again, I noticed a few things. First, it looks like he's trying to get practice drawing feet again, and that's good. It's nice to see a comic work to try new perspectives. I also noticed we can see Roger's teeth (I can think of only one other time we could, and that's because that comic also struck me as odd until I realized what was different), and on a closer look you can see he's actually missing a tooth.
...I wonder what it says about my webcomic reading habits that changes in perspective and attention to detail are significant enough for me to comment on.
