I can't seem to make the images work. It was mid afternoon, very flat light, low tide and the locals were taking advantage of a hot water spring that rises through the sand. The images look so flat and empty. Can anything be done PP or is it a re- shoot? Any comments would be gratefully received. 
My guess is the experience you felt in being there is not coming through in the photographs.
The view is distant, more so in the second than the first, so creating immediacy and dynamic is automatically more difficult. However, Peter’s representation simplifies the concept into a set of shapes set against the interesting sky. I think he’s done about the best that can be done. Not every set-up, scene or situation will be a keeper.
If you can re-shoot, get closer. It can work without depth (almost like a set of line dancers), but that’s what you have now. Decide what’s most important: what the people are actually doing (more documentary) or the shapes, tones, lines - the aesthetic - of the scene. Good luck! It’s not an easy situation to capture in a single photograph.
