Bob uses a round brush (that I have been unable to find anywhere) in this painting and the difference it makes in the texture of the trees is definitely noticeable. This isn't my favorite painting but I am happy with it as it's my second Bob Ross painting. This was my first painting using linseed oil and making my own liquid white. I really learned how to use thinner paints to get the texture I wanted. Although I'm not in love with the outcome it has been a learning experience.
