Much more is needed than just a nice photo to make a successful painting. Fortunately I don't take many good photos. Here's an example of things I'm still learning as a painter.
I'm often asked how long does it take to finish a painting. That's difficult to answer. I'm not always sure when a painting is finished. I plan to work on another painting or 2 based on the photos and what I remember from hiking that day, and also working with what I learned painting this one.
