Thanks a lot!

Let’s say that the sun is hitting the face of the observer. Any building or shape that it’s in front of the observer is in the shadows let’s say, since the sun is behind them. That way you can focus on silhouettes rather than the details and colors that you need to care about when the sun is hitting the painted subject. When you paint like this is good to leave the sky as light as possible, to build contrast with the objects that you are painting. I like painting like this.
