Some general comments:
I would like to see the designs on a background similar to the banner at the top of my site, so I can get a good idea of what they'd look like on my site. The gradient currently on the banner is available here:

I don't like rounded fonts. I prefer the fonts in #48, #43, #50, and #88, for example.
I definitely want to see a solid, standalone graphic of some sort, as you can see by my rankings. The graphics in #48, #78, and #81 are the sort of thing I have in mind. #43 too, if it can work on a dark background. That said, I could make an exception for something like #50 if it were fleshed out a bit more.
