This map represents a mountain pass with very little vegetation. When playing on it, I would recommend having the cliffs be between 10 and 15 feet high, as to make it difficult to cross over them without being nearly impossible. This will allow characters/enemies with climbing or flight speeds to shine. There are also several small trees growing out of the cliff face. I placed these for aesthetic and so that any plant based spell isn't rendered useless. If you want to make the cliffs easier to get up and down, you could have the trees be easily climbable. I additionally used the brush tool and a nearly transparent black for the lower levels to help them feel deeper.
