Lineup of Sketch 4 trees. Colors and values don’t really match up side by side but that’s intentional for the final look with scene lighting and fog. Initially I had the colors and values closer together but that ended up looking a bit boring and unrealistic.

One neat thing I figured out but didn’t really use much as I was already wrapping up the scene was to paint ambient occlusion to the texture. You can see this a little in the small spruces far right.

It adds a bit of depth to the texture but, being direction independent, doesn’t restrict you form changing sun position.
