Perspective Composition

I found a bit of an interest in Perspective Composition so here are a couple pics in which I have taken that I feel falls into this category.....

Perspective Composition is... (my take) the positioning of objects to which the image produced seems almost 3D.

to me this one seems to make the cow stand out as its in front of the barn (I am across the street & have zoomed in on the images)

this one seems to have a 3D sense to it as well as I am close range and the details seem to "pop" and present themselves.

This is another article that I came across in my readings...
