Example: On the right you have what looks like some weeds I'd anticipate to be about 3 ft tall at the most. Then you have structures on the left that look about the same height if not shorter. Dog houses? That would put the structure in the middle at around 6 ft-ish. But...if all of a sudden you added a human model that would fit into the smallest structure..the others would suddenly appear to be huge. Make sense?
