I don't feel that all modern art or all digital art is bad.
Angelic Destiny and
Spectra Ward are very obviously digital but they're also some of my favorites from more recent (Magic 20XX and later) sets. Sure, my all-time favorite M:tG artists are more Terese Nielsen, DiTerlizzi, Rebecca Guay, Mark Tendon, Anson Maddocks, Richard Kane Ferguson, Matthew Wilson, Susan Van Camp -- that sort of set -- but the currently favored style doesn't fail to please. Heck, I think I got less pleasure out of 7e/Onslaught/Mirrodin art (The
Fascist Art Director Era), which had a good deal more "traditional" pieces, but driven to directions that I didn't care for.
That said, I do think more recent offerings have been missing something. When I think about old M:tG art like
Curse Artifact,
Mana Matrix, a ton of stuff from Fallen Empires like
Ebon Praetor... Stuff from the era before style guides, there's a weird inventiveness that's been missing. And I understand that was part of an exchange. As of Mirage, creative started making sure there was a real theme and direction for sets. We lost some of the bizarrely creative designs that felt weird and magical in their own right, but we gained a constructed universe into which it felt like the cards actually felt, grounding them in the lore. I absolutely love the art from the Rath Cycle and Urza's Block and the style guides developed for them are no doubt part of it. But you know... every once in a while, I want to see something that actually gives me pause. That makes me stop, look at it, and imagine what sort of bizarre and mystical realm I've planeswalked into to witness the vista before me. I think the last time we really got something like that was
Future Sight, in particular in the Futureshifted subset. Magic 20XX wasn't totally bereft of this, I mean I can't place the plane of either of the two pieces I led with, but overall it didn't really use the opportunity as much as I'd have liked. Ditto some of the weirdness from Commander (whatever).
