Hmmm... I think I've seen it already about a year ago...
Anyway, it is not too logical: water streams with angle, not strictly down as it should; gates are bigger than the fense, not the same height as they should; garden is close to highway while there is vast empty space around it - how'd you relax when cars are moving near your ears?
There is a lot of unused space that makes the picture look boring. Try adding some flowers or something to give it more color.
