These are great! I really like the sixth design down. It would like great as a poster/billboard. I like how you incorporated the logo design into your layouts. Good job!-Kylie
#6 I like how the you have one part of your logo and then the swimmer going down. Its really interesting layout. It's a good contrast, if you have all the columns it might be too much. This kind of design is able to use in other sports. good job-mary
I like how you have the athletes interacting with the graphics. Maybe the 7th thumbnail could be used as the billboard with a die cut of the graphics.
I agree with the rest, I like the 6th and 7th design. They follow through with your logo, and they'd make good initials to a poster or billboard.
