Here is the painting "Sun Kissed Drive" that I will be talking about. As you can see, I organized my light and my shadows and made color changes throughout the painting. I am going to talk about the porch detail below.
The detail on the left is from my painting. The detail on the right is a detail from a painting my student did. As you can see, I have painted the structure of the porch. The posts in the back are darker and remain back, while the posts on the front come forward. My student stopped looking at what was in front of her. She just put the posts in as she imaged them. They look like they are lined up in the front. and they don't go back. This is what I would call the structure of this side porch. It is important to visualize this porch in space and to paint it that way.
