LOL! What a novel approach to the challenge! From the scores, it looks like some folks just don't step outside their boxes too often, do they? It may be title-dependent, but this is very clever - your shots show great imagination. Colors are very nice and rich - I like the yellow of the house with the blue of the water and green of the trees. I'd have given this a 6 or a 7.
I like the concept behind this photo and the visual cliff formed at waters edge. The colors are rich - the greens and blue are very compatible and pleasing. I do think that the site of this picture is busy because of all the trees. The simplicity of the water doesn't carry over into the background. Now I realize that you can't go around changing trees, houses, and the like, but I do think it makes the concept harder to execute when there is so much going on in the background. This photo definitely has a unique perspective going for it.
