To-may-to, to-mah-to.
I like the art in every edition, although I'm not very familiar with 2e's art, as I never played that addition, except for seeing covers and the like.
What I truly loved about 1e art: the evocation of adventurous images, and not just heroic character studies or still-shots. Pictures like Emiricol the Chaotic riding hard through town, being chased, or the cover of the PHB...you were looking at a story
in progress, a tale being told that you wanted to know more about. 3e has fewer examples of this, though it does have it. One of my favorites is Tordek and Regdar attacking the drow wizard with the staff as the ground explodes around them, for example. The picture of the adventurers in the tavern, checking the map is another.
The incorrect assignment of the term 'anime' to the current art has already been discussed multiple times, so I won't go into it again, other than to point out that if you placed Hamtaro, Master Keaton, FLCL, Lupin III and Fist of the Northstar side-by-side...you wouldn't make that claim as readily, if at all.
What I do think they need to scale back some in 3e art: too much mish-mash. No one has a simple set of armor any longer. They're all like Hennet, with what looks like pieces of four different outfits thrown on at the same time. Some leather here, some chain there....that's fine once in a while, but could we occasionally just have a guy with chain and a tabard, wielding a weapon, for pity's sake?
