AC 1,2,3 are made of awesome. (I miss nine! I might just rewatch season one again soon!)
I also love all of the one cap/pic icons. Because I love New Earth and the sight of anything New Earth related makes me ecstatic and giddy because that episode is my favorite watch it when I'm depressed so that I'm happy again episode!
I also love second look (Idiot's Lantern being my other squee episode), love, and sky.
I sense a picspam coming on. :-D Sorry for this long chatty post just to say that I love your icons but I'm trying to be less shy and leave more comments!
