My son said . . what's that got to do with contrasts?
Well, it's the contrast between the scruffy scarecrow, and nature in the form of the sky and land -
there's the contrast in the scarecrow itself, between the 'high tech' CD and the old fashioned construction and clothes.
In addition there is the contrast between the man-modified land, and the splendidly free and wild sky.
LOL - I can't describe this sort of thing - the point of a good photo (to me) is that it should be full of ambiguity and clarity, seriousness and humour, structure and chaos
. . . in this case I'm not sure how to put it into words Sorry!
