But yeah, some of the lines look artificial. remember that areas further away from where the eye is focused become fuzzy... if you mean the eye to be focused on the couch, then the distant background should be slightly out of focus. Neither camera nor eye has that depth of field without sacrificing something else. Also the shadows on the sky look a little out. I don't know if that's deliberate though...
Haha.. this is a great picture though. At first glance I didn't know it was a manip, but there are some things that you might try to work on. For starters, the division between the land, water, and sky are so perfect. The horizon is perfectly straight, something that may be technically right, but looks kind of odd. Try adding a vanishing point to the sky as well, simply by constraining it into a triangular shape. It looks really cut and paste right now.
The cought, pier, and tree-thing are very nicely added.
