Of all the propeller caps thus far, I like yours best. I would be interested in seeing the text larger and the cap smaller, as well as the cap straight on (rather than looking up into it) and the propeller black rather than gray. Good start. By the way, I like your work on Silicon Fruits (the pink and green ones).
Entry #8 is a definite improvement and getting closer to what I'm looking for. I ranked it 2nd at this point only because I like the font choice better in the one I ranked #1. I would like a font that's not quite as bold as the one you chose somewhere in style between the first and second font used, and would like to see a straight on perspective on the cap with shorter blades on the propeller.
As for horizontal vs vertical, both have their advantages and appeal. I think once we get the font and cap right, we can experiment with both. Thanks!
Okay, as I noted elsewhere, I have decided to go with a horizontal design on the logo. So, if you could place the image to the left of the text in a variation or two that would be appreciated.
