This is my first contest and I just found your comments. Thanks for the work and your well articulated synopsis. I will try to provide constructive input about your design, but ultimately, the perfect design is totally in the mind of the beholder. Or stated another way, there is no accounting for taste. I tend to like the logos that are done on a white (neutral) background. That way they can be applied to any media (web, t-shirts, etc.) without the media background having to be a specific color. I like the idea of what you have done, but I don't like the actual logo that much. The symbol sort of reminds me of Pac Man and seems to be a bit 'industrial' looking. Again, it's all in my mind. But in terms of the idea of what you are doing, it's totally on track - bold, simple, visual. See my latest public comments about the logo for SailingAnarchy. I hope that you will stay interested.
Best Regards
Mike
