Number 4 is interesting but looks more like something that would be used on letterhead as opposed to a logo we can use across all channels of media. Entry 2 is interesting. i would like to see this one developed more with some different elements and ideas.
I think that entry 12 is very creative. It looks rough since it is the first draft and I would love to see some additional concepts with some bolder colors and fonts. By bolder colors I mean the same types just different shades and thicknesses.
