Ok, so I know it's not your fault that the people's umbrellas were red in the first two shots but I'm gonna tell you to be wary of spots of red in a shot.  It's the most eye grabbing color and a lot of times distracts from the focal point of the picture (unless, of course, it is the focal point).  Like I said, it's not your fault just keep it in mind while shooting.  It's more of a problem in Surf Fishing than in Beach Parties.

That being said, I really like the last two.  Espeically the last one.  There's something very expectant about the shot and you captured the emotion of "the approach" very well.
