So this brings up an interesting argument--where it appears people have not improved when...they have, it's just in ways you can't see.
We always assume that all art improvement is visual, but it's not. There's a lot of things going on behind the scenes that you may pick up if you're a more advanced artist (so we can look at things and be like "wow! look at that improvement!") but if you're new to comics you may look at the same thing and see virtually no improvement at all.
Such nearly invisible to the untrained eye improvements are: pacing, storytelling, composition, speed, flow, texture, colors, lighting, line delivery, font, bubble placement, length of episode, speed at which it was drawn, relatability, appealing character designs, etc etc.
WLOP has art that is very clearly aesthetic, but bless them for how beautifully it's painted, it really suffers as a comic. I won't go into detail because they're well loved but I really wish that for how talented WLOP clearly is, they took the time to learn how to do a comic. They look absolutely perfect if you're a beginner, but if you're trained you can look at it and be like...
...I can't believe WLOP is still using that font and those nasty see through panels...
So in your own journey you have to look at more artists than just WLOP. You can't just rely on rendering. That's what I used to do -- I used to hide the fact I couldn't pace a comic behind just rendering really well. But you need to look at other comic artists who also set the standard without the need to render like that. Comic artists who are good at paneling, who are good at showing emotions in their characters, comic artists who are making comics their dayjob.
