I thoroughly like the concept you're following here, Harmony, my issue with this photo, though, is that the silhouettes of the persons that cast their shadows onto the deck (is that the word?) are so very mixed with the background so they get all lost. You may have thought that their shadows alone make the photo but I don't quite agree. Maybe if you had knelt down to make at least their heads (maybe heads and shoulders) appear above all that's behind them, then I'd think, wow, cool. For, like I said, I do applaud the concept you are following here. And the way the low sun makes the texture of the deck come out is fascinating!
