I think this image captures a lot of my feelings between old-style art and the newer digital stuff, and the tangible differences between the two.
Not to dredge up the shitposting, but I think there is a pretty major difference in the way things are approached. Fantasy is "solved" now in ways that it never was in the time the "older" style of art was produced. Think about it this way- something like "a dragon" is a pretty universal concept, but what about "a wizard's spell"? Now, we probably assume flashy magic circles, certain poses, and fireballs, because that's what we expect.
There was less to "expect" for this older art. And believe me, I'm not trying to say that it wasn't formulaic (how many of these are bikini-clad woman, ugly and or beefcake male, and intimidating beast, in various poses?), but the expectations and freedoms were different.
Like the picture here. What the fuck is going on in this image? What is any of that? It's up to interpretation. This image could be taken as "travelling to the great wizard's tower by ship", but so much can be inferred, without confirming any of it. Maybe the old guy is a god of the sea, and lead the ship here. It's open-ended fantasy.
Again, not saying you can't get this now, but the feeling is different, and the vast majority of what is being produced basically has to adhere to very static and flat tropes because that's The Way Things Are. We don't get cool, otherworldly, symbolic, psychedelic wizard spells anymore, because the wizard can't be more powerful than the other classes, and has to cast simple, understandable spells.
I don't think the fault lies with the tools, nor the creators. The fault lies with the culture, "playing it safe", copycatism, and fantasy being a much more openly known concept than ever before.
Obligatory "thanks normies" here.
