I've been human, the early version of vampire, devil imp, zombie and the black/grey Dark elf.
Once I went black, I never went back! I don't know, I just like the dark elf base for some reason. I do also like to play around with my base though, and I change my avatar outfits often too.
I don't always want black skin, so skin items are fantastic to me, I try to collect them so I can have some variety if I need to. But my base stays the same smile
It can be hard to work with, but I guess I'm just kind of used to it now and work around it without noticing. I'm not a really good avatar builder and I don't tend to get very fancy at all, so most of the time what I'm doing works okay. Feels weird being human now though!
I'm not female so it doesn't usually affect me, but I have noticed the major downfall of the base is make-up, and some face mods. Some work, but others just look really super bad and wrong. Most of the rest of the problems is just that the base is skinnier, so some clothing doesn't fit quite right.
