The next thing to finalise was the background. I quickly went back to my reference material and picked out a few elements that I thought would make interesting additions to my illustration. I started from the top, adding the waterfall first and suggesting some rock faces in the background. I then worked my way down creating the vines and tree roots that all act as guides to lock the eye onto the central figure. I added texture to the foreground tree using another custom brush (Fig B), and gave its surface a 3-dimensional look by zooming in and picking out individual highlights with a three pixel brush. Another custom brush provided instant vegetation at the base of the tree and on the opposite bank; these were some of the last touches I needed to make.
