Oh! I loved that series! (and the book even more!)

Let's see. I haven't taken any, because I'm on the wrong computer (when I have the right computer, I plan on raiding many of your icons). But I liked 2 (color and the blur), 3 (though--it looks like there's a megaphone in the background...?), 4 (color--and I think there's a bit of soft glow? it's very cute--I also like the crop), and 9 (color, crop and text).
