Detailed landscape drawing

This drawing took around 5 and a half - 6 hours in total. I had to adjust the brightness and contrast on this one only because of the details on the ground.
The composition was based upon the rule of thirds - keeping the close and the far edge of the barn on the 1/3 lines and another thing I was looking for was diagonal lines - to show more perspective(2-point perspective again, as the barn wasn't high enough to give a realistic and visible result in 3-point perspective) and make the overall look more dramatic.
The drawing shows several depth levels with the thin tree and the closer edge of the barn, the small wall on the further part of the barn and then, the trees behind the barn and the net next to the barn.
What I like about the drawing is the level of detail in the walls and the rocks that they are build of. Another thing I am happy with is the way the ground and the roof give a hint about their texture without being too detailed.
I decided that I shouldn't add shadows and shading at all, because it would have made harder to see all the little marks I payed attention to.
