This is a new large painting. I got the reference photo from my father, I have put him on photo duty and he does an excellent work. To be honest, he is in better shape than me and he is 83 years old.
I usually pick only part of a reference photo, the feeling, some details, the colors etc. I don't pay much notice to the trees, which might be odd. I might take some placement suggestions from the photo though.
Not the best photograph, but I took it to show the size compared to a 6" x 6" painting.
