I don't particularly like them. They're not round, the colours aren't really very pleasant.. but they're not bad in general.
Yes, I meant them to be kind of between a circle and a rounded square since a bunch of people were doing square or rounded square emoticons on Pixelation. As for the colors.. they look great on my screen but I'm on a laptop and although it's the most fantastic screen I've ever used, apparently the saturation is lower than many desktop screens, so I wouldn't be at all surprised if they're painfully bright on your monitor. I don't really know what I can do about that without ruining them for other people, especially when I don't know how they look to you.
Anyway, thanks. =P
And moldy.. the only thing that's over-AA'd are the eyes on a few of them. And that was because I liked the effect. Well, and the mouth on the shocked one, but it's not that bad and I'm too lazy to spend any longer doing it over.
