Forest sketches! (Patreon)

Ah, forests... My worst enemy.
How do you paint one? Focus just on one tree? Try to paint as many trees as possible? How do you set up the composition when it's all vertical lines...
And by definition, it will take a long time to paint because, oh, so many details to paint.
This forest painting is supposed to be a part of the series of paintings that I've started a while ago so I have to incorporate a few stone monuments to match the previous 3 paintings.
These are the first 3 sketches but I want to do more and hopefully I'll find a composition that I really love. And all the different sketches will look nice as a portfolio submission.
I think they look ok, I just feel like there's a better option out there to figure out. (There always is)
