It's a very overwrought and hyper-dramatic style that Wayne Reynolds uses. You've got huge, almost excessive detail, heavy, heavy anime influences (I mean one of the guys in that picture is Vampire Hunter D but with a bow), combined with Western comics influences, specifically 2000AD, which he used to work on, and was clearly influenced by the other artists there. It's definitely not at all realistic, so the idea that it's accurately depicting a D&D character is pretty far-fetched unless they have multiple costume managers (aka squires) following them around and helping them get dressed.
Sorry, if I gave the impression that
realism had anything to do with why I like the aesthetic (which is not exclusively the domain of Wayne Reynolds, though his work, particularly on Pathfinder does exemplify it), I’ve miscommunicated. The gear D&D characters tend to carry is itself highly unrealistic, and I find something very satisfying about the effort to actually depict it all.
As an aside, I get a similar satisfaction from Mass Effect, especially the first game, because of how the guns fold up so they can all fit on the character’s body, even if you’re using one of every type. They’re incredibly unrealistic designs, but I like that they actually
show all the crap the character is supposed to be carrying despite its lack of realism.
On the other hand, you can see the realistic roots before it's taken to this excessive place if you look at British fantasy art in the 1980s and earlier 1990s. There's a sort of hint of this gear-fetishism even in stuff like Lone Wolf - and it took a while for Reynolds to get there - his earlier work was less wild.
Gear-fetishism is a pretty good term for it
But, yeah, I
like the excessiveness. There’s certainly a point where it can get to be too much, but for me it takes a lot to get to that point.
That said, it's definitely more extreme in terms of how complex and funky their gear and outfits are than both the previous generation of fantasy art's armour, and the following one, the pink-and-purple "steampunk" one we have now. Even the art of stuff like FFXIV and WoW features less ornamentation typically (FFXIV is somewhat closer to Reynold's Pathfinder work than WoW is, I'd personally say).
Yeah, I’d agree that Final Fantasy, basically from VII on, has a similar vibe going on. Tends to have more tech than I go for in D&D, but it’s definitely playing in the same aesthetic space. I’ve never actually played any Final Fantasy, but I do quite like the aesthetics.
