Big Rock, Trees, and River (Graphic Novel filter)

I really liked this picture from a number of years ago. I like the odd shape of the trees and how they are growing. I like the rocks. What I don't so much like is what I see when I look at the image up close and see purple fringing where the image has white light spots. 

So, I made a graphic novel filter version of the image in black and white. I didn't colorize it, because the purple would still be there. But I like looking at this one up close, for all of the lines in the trees, the rocks, the branches, the roots, etc.

Thanks for stopping by and looking at my pictures! :)
