I like the theme for the picture - nice and peacefull. The one thing that feels a bit odd about it is that its sense of depth seems a bit out. The foreground, up to and including the rocks the people are sitting on looks fine, but the background trees seem to get small (due to increase in distance from camera) far quicker than the amount of along ground distance between the people and the trees would suggest. You could try making the trees bigger, but putting them (and probably all the other background stuff) a bit further back from the people. That might help the depth thing (hopefully).
