Over the past year, my avi style has shifted fairly dramatically.
I went from a demonic black and red and gray and white succubus style avatar, to a sherbet rainbow cmyk bright. Still often demonic, but not afraid to go a bit cute.
Not entirely sure why or how the shift happened. I've always loved rainbows and rainbow items, but there never felt like there were enough to make a decent avatar out of them.
And now, with the influx of cmyk, rainbow and pastel rainbows, I'm spoilt for choice (and forever questing)...
So I think it's more a latent love that's finally actuated.
