nice. perhaps without the house it might be more surreal. had you been able to bounce some light in between the front two trees to reveal the object there might also have added to the overall effect. not sure what that object is and would like to.
Wow, they look so human. Like druids :) I wish you took it from an angle, where the house in the back would not be visible. But I know how difficult it is to shoot in minimal editing. (Just commenting - no voting).
One must assume there are trees inside the burlap sacks. I guess we can use our imagination, because you didn't show any trees in your composition. I did score this fairly well, because your DOF is excellent. Exposure is very good. It's a "think outside the box" image, which is usually punished by the punks at DPC. (6)
