Just to be more clear;
I'd love to see more yellow in the skin. When I make a reply, the window changes to a yellow, and I think it looks really good with the brown background. I'm thinking less blue, and more yellow. But I'd keep the green, I think it looks good. (EDIT: Looking again, I'm seeing more yellow-green-yellow, which I think looks good, but I still don't see it in threads, which is what I really meant.)
I also think there should be more bold greens on the site, like with the reply button. (I'm diggin' it)
The buttons up top like home, or help, look off to me. I think the text could be brighter, and I don't get what's going on with some of the letters being grey.
A lot of this skin seems to center around icons, but I'd personally like to see more words. That might seem odd, seeing as this is an art forum, but it's my honest opinion.
What I mean by it centering around icons if that the words are either darker than the icons, or non-existent.
