Watercolor Realism

Watercolor has been one of the  toughest mediums to deal with and I can proudly say that this is my best watercolor painting made on an A3 size sheet. It displays a traditional vintage house with crooked windows and doors and old rusty walls with a water pipe running down on the right corner. The accurate display of  shadow falling from the neighboring houses on the wall is what I think gives it a realistic touch.
