Arg this will be embarrassing for me but, hahah my comic really IS the best measure of my digital progress. I was primarily a traditional artist up until 2013 when I really started up with digital. (It also didn't help that, at the time, I had a broken tablet so, that wasn't fun. Often I'd have to finish my work using the touch pad on my laptop.)

I know that last one is in a bit of a different style but it's the best example of 2017 that isn't a comic page, haha. And just to show you how hard it was for me to acclimate to digital, here is a drawing I made in my notebook in 2013:
Yeah, my digital stuff seriously took me forever to get closer to the style I have IRL and I'm still not there yet. I've got a lot of improving to do, for sure. XD
