Urban Sketching - a hill and a windmill

I leave this upto viewers imagination. ;) This hill did not come out good :)

I wanted to show elevation using foreshortening technique. unless explained, it is difficult to visualize. :)

A Windmill :

Practicing cross hatching. I feel it came out decent :)
