I am 'not fond of them' officially. There's occasional artists that are quite good to actually brilliant, and most of them get that way by subtly or not-so-subtly breaking away from dolling, it seems. I don't enjoy the concept of using other people's bases both because it creates this odd 'respect-based' clique mob mentality and because it potentially propagates mistaken techniques. It's the same faults that make 'Advanced Sprite Art' tutorials out of pillowshading. Just too inbred, not looking enough at better art by better artists.
Which isn't to say that most other pixel art scenes don't have similar problems, but it's particularily visible in the doll stuff. Moreover I find a large section of the doll art I've seen extremely aesthetically displeasing for various personal reasons, but nobody asked about that so I'll keep quiet. That it's a scene mainly frequented by 12-15 year old girls also may be a nebulous factor determining stuff, though I hesitate to guess what and how. I'd like it if some of the resident were-once or still-are doll artists could paint a picture from their experience.
