I kind of like where you are going with this ( I like your style). I think my ranking may have thrown people off a bit but the first rank was the best I had seen so far. I would like to see another variation or two along the same lines as what you have here but maybe with the symbol being a bit larger, perhaps a bit more edgy, and I think I am starting to like the metalic brushed aluminum/chrome and purple in the color pallet.
#18 is my favorite so far but I think I would like to go in the direction of blue instead of purple. Maybe a dark blue. Can you submit on like this but with the symbol being a darker blue (your expertise in the shade of blue is much appreciated)
