so I got this picture that I want to use to make a stencil to project on a wall and paint. thing is I'd like to clean it up a bit since I only want the trees in the background and not the big one in front and the black grass. I tried playing in photochop but I suck at it. Anyone wanna help to just make the trees more "present". here are the original in blue tone and the one I tried to fix in greyscale sorta..
