I guess you are trying to make it clear that you don't want a level picture. We are supposed to be seeing the green grass, and noticing the color, right? So many trees in the background, I actually want to see the row of them level and straight across the background! This looks like a big park. A walk in the park in the afternoon is one of the greatest places to practice photography I think. There is always some new people and the plants and weather are always different each time.
