I've had these for a while and haven't really used them very much. This was a great lesson on techniques to make them a part of my sketching more regularly. I love how you can layer them up! I was just going to splatter a couple of greens on the tree and some other greenery, but lush green looked so pepperminty wrong I ended up adding a bunch of olive and activating all of it to cover it up.
