it looks almost real, only problem is the sky, it _should_ be brighter. its a must. its really... dunno how to put it... "poping out" of the whole picture, it feels out of place. compare sky brightness with front wall of the house, theres too much difference. if you would just change its brightness/levels it would be perfect
also, its a bit too purple, maybe you should adjust hue a bit as well
other then that, really good job
