Hmm, here's a comparison from an earlyish page of my first comic, vs. a snippet of the first episode of my upcoming new project:
I don't think my style (especially the way I draw human characters) has changed too too much, but the change to digital line art rather than traditional and my increasing experience using digital art effects definitely shine through.
Admittedly the top old comic example isn't as representative as it could be, because I didn't skimp on backgrounds as much as it might suggest, but I've also been trying to flesh out my backgrounds more as well. When applicable, a little texture goes a long way. Or even on simple backgrounds, a little gradient or accent color goes a long way vs, flat color areas like in the top example lol.
I've also been trying to simplify the way I shade lately. In my first comic I remember I would intricately shade every little piece of every panel, even in mid or far shots. I still spend the time to shade everything in close ups, but try to leave things a little simpler otherwise. The time savings from that I like to reinvest into lighting layers~
