Entry #8 is very nice, we like the tree/umbrella presentation. Entrys #26 & #27 ..... we are not so sure about because we are not sure the reference to the dollar is where we are going.
#48 is fantastic..... love the shading on the umbrella.
I know your design is quite clean, but it has been requested that we incorporate a man with a monocle yelling to integrate the marketing aspect. I posted additional feedback from the group on the main page of the contest as well.
