Human-Made Space

If I was to create a landscape with natural materials, it would definitely have to look like it belonged. I would use fallen branches to create a 'tree' in the forest. I would used tons of stone to create a small 'mountain'. I would even like to use fallen leaves, seeds, and maybe fruit to create a 'garden'. All of these things would give the appearance of the original without ruining the look of the natural landscape. Something that brings an illusion to the eye and a smile to the face.
