Here's something from the archives. One of the oldest drawings I've got, and maybe one of the first with color.
I'm talking about the two in the middle, the ultra beta Sara (when she was going to be a tiger) and cracked out of his mind ultra beta Mike. It was made probably around December 2015.
The two characters on the outside are later versions of Sara and Mike probably from early - mid 2016 when their designs were more finalized. (still well before the current comic was started)
If you look closely you can see my early (obviously knockoff) working title for an early comic, and Ryan bleeding through the page because I drew him with one of those liquid pens and a sharpie.

I've got tons of old crap like this (probably 100s of drawings), but none really scanned into the computer. Let me know if you want to see more of this stuff, then I'd be motivated to scan more of them in.
