Rob: Thanks! There are a few things that I'd like to make look a bit nicer, like the comments boxes, but they've been causing my problems whenever I try and change them. Aside from those, i'm pretty satisfied.
JGray: Honestly, I like that they're uniform. Anything else would feel kind of messy to me. Also, I didn't make them. A fellow on deviant art made a pack of them for social networking tools, and presumably used the same base for all of them. As such, i don't have the base PSDs and can't really edit them without royally messing them up.
