To be blunt; to me these look either amateurish or bland. If you read through my comments you'll see I'm looking for an elegant illustration, which character. A set of simple, straight-lined triangles I could do myself. It's nice to see your ideas, but the winner will, I believe, be a logo where there's an elegant, detatched graphic to the left of the text. See #22 (the current winner) for a perfect example.
