Watercolor painting completely depends on this mantra! I was just about to start finishing the buildings on the right, when it hit me: do I really need to paint 50 windows, the roof with all the chimneys etc. to call this painting done? Will it add anything that would make this a better painting? I think not.
In fact, I think it’s better not to finish it. For some strange reason, your eyes are putting those windows there regardless! Almost like, we know they’re there, so we don’t need to actually put them! Also, I did not like the fact that the tonal contrast (being very strong) on the buildings would take away from the focal point lower in the picture!
As I always say: each and every watercolor has a lesson to teach us! I absolutely love it! All we have to do is paint and we never stop learning.
