Surfing Art

I'm currently working on a series of illustration with surfing as the focus. There's going to be 5 seperate pieces (2 vertical and 3 horizontally-composed so it'll look a little something like this....
! - - - !
The first piece would be of a surfer (probably from a back view) with his board looking out to the ocean.
The last piece would be more focused on the ocean at the end of the day (sunset) with the surfer walking away after a succesful day of surfing.
However I can't think of what to do for the other three pieces. I know one of them would be an actual surfing picture, but the other two elude me. What do you guys think would be best to go there (It's sequential)? Or what aspect of surfing would you like to see illustrated?
