This is my second attempt to watercoloring a window. I hope that I did it justice. The photo was taken by my father on one of his trips.  One side of the window is open and I am wondering if you all see that or does it look strange? 

My first attempt of a window was a window in Italy.  I used no ruler for it which I did for the second one. I am still getting the hard watercolor lines. Any advice? Also what can I do for storing my watercolors, they dry up so I think I am over saturating them with water. Can you give advice to storing tubed Watercolor. Thanks so much for the class. I love taking them.
