Currently, I'm using Infernal Smash. I love the orange and red color scheme, and the banner at the top is quite attention-grabbing. It's a bit large, but still nice to look at. Would've liked it a bit more if it was sharper, though. Before that, I was using Conway. The anime pictures at the header look very pretty; they're extremely bright and colorful. (: I feel that this theme is a little underrated. In my opinion, more people would be using it. Give it a try, guys!
