Not a very good beach day was it? I see where you're going vis a vis negative space in this, but I think the view in front of the people is as much a focus of the shot as the people are. So, it doesn't feel very "negative spacy" to me althought I'm sure there is some "truthiness" to it. :-)

I think this is a nice creative use of people in the scene. I also love the colors in the water.

Too bad the people are facing away from each other though! I think it gives the photo a strange detached feeling that doesn't seem entirely intentional.

I think this is going to be a tough theme. This image isn't about negative space to me. It's a landscape with 2 people squished in the corner. I think a different composition which eliminates the sky and gives a slightly heavier emphasis on the people would have worked better.

Horizons have just got to be level imho! Otherwise super take on the theme!

I really like your composition. I wish the horizon was straight though.

Good composition, but I don't consider the open ocean to necessarily be negative space...

Appears to be in focus. Could use, IMHO, some jucicious framing.

this actually works, nice
