It looks good. Would still like to see it with other colors, although I do like that orange. Also, if the line for the Q only went part way into the circle, instead of all the way across, would that make it more recognizable as a "Q"?
I like #102. I wonder if the border could be green on the bottom, and blue on top (like grass and sky)? Then the white cloud in the middle would be set off. I would like to see it a bit bigger so the border is more pronounced. Also, no shadow's please. And try some color options with the "Q" and the "2". This is very nice.
I'd like to see #132 with the slash in the Q separate from the top of the 2. Maybe have the slash come down at a bit of a steeper angle, and just have the 2 connect to the gray. Right now I'm concerned that it's not clear that it's a "Q" in there. It looks a little more like O2, rather than Q2. Can you play with that to make the Q a little more obvious?
