The trees in the foreground are tall and seem dramatic, this is mainly to do with their bold upright trunks that draw your eye upward. Having said that the autumnal colours in the distance are tremendous, this draws your eye along the path and into the distance, the combination of the tall trees and the bright autumn colours draws your eye to the clearing in the centre where the two meet and to the vast sky beyond. This expanse is what gives the illusion that the trees are so tall. Or perhaps… perhaps the trees are just really tall! I suppose we will never know.
