We prefer #5.. perhaps there is someway to merge the two (#5 and #6)? We like the black background AND the red tie, or, more importantly, the red aspect embeded in the image (it doesn't have to be a tie). Also, could you change the man to be more cartoony? We believe the man as you have proposed it is too formal and conservative looking. Lastly, we like the lower case font. Is there another lowercase font we can see this in?
