Hi mttorley,
Thanks for your comment.
I didn't really use and special techniques on the background. I created 3 new layers and one I filled with the medium shade of green using the 'Calligraphic pencil default' brush with it's default size and opacity. With the same brush, I did a few quick strokes across one of the other layers in a darker shade of green and a couple of quick strokes with a lighter shade on the remaining layer.
Hope this helps!
