This one is watercolor on A4 size good quality paper. I found this one on YouTube and thought it is a nice effect. What I didn't guess is the work time. usually I am quite patient. I painted some Bob Ross paintings which I needed more than 5 hours, especially in acrylics. But to paint the trees here with a liner brush was too much for me. I almost gave up and did not want to finish, later i just painted them in very roughly which I think doesn't look good. anyhow I thought I share it, maybe someone likes the idea and has the mood to paint this exactly.
