6 is the coolest design, in my opinion. I just dont want to project a dog type image. were are a legal software / law office management system. I really like your designs, just simple and very very clean. trendy, modern and hip. would like to see this design with a different grafic, maybe scales of justice (in the same very cool sytle of course), or maybe a slick 2 or 3 drawer file cabinet, or something that projects law or office type product.
i also like the way you put the legal under the top on number 9. not so sure about the little puffy cloud on 9, would perfer the dog to be in the color of navy.
