It's a lovely silhouette but I do think that the blue is a bit on the strong side, on the border on surrealism.
It's also disturbing to see the things on the water on the bottom of the pic. Personally, I would have crop them off or tilt the camera a bit more upwards.
Last, as a city resident I can't express my envy enough. I'd kill for such a backyard.
thanks for the suggestion on the foreground, ill give it a try next time i take some more landscape shots of my property. also, the reason i did not tilt up is that you would then see the City in the background but now that i think about it, instead of having the camera about 4ft up on the tripod, i could try putting it closer to the water. anyways, I'm just fortunate enough that my mother has 22 acres on the edge of the city.
