Directed Study Week - Landscape

This is what I drew in the directed study week, took about 3 hours in total. I was aiming at ending up with a detailed landscape drawing while taking into account perspective, composition and light.
As my previous drawings, this shows 2 point perspective (I was thinking on intentionally drawing in 3 point perspective, but that would have forced me to look up at a tall church and I didn't see any good composition opportunities there). The perspective should be obvious in the main outline of the building and the fences and the wall on the left, besides these I also tried to use perspective to give a little depth to the tree to the front (not sure if it worked).
As for composition, this time I decided to place the horizon line on one of the rule-of-thirds lines instead of putting special areas in the rule-of-thirds points and after that i just looked for a view that was visually appealing to me only trying not to leave any objects too close to the edges of the drawing. I chose this drawing spot because this way I had a tree really close giving me the opportunity to try myself at doing a fairly detailed tree, plus it fell perfectly into place right next to the building, filling up the otherwise empty sky. Also, the wall and fences to the left happen to break up the otherwise boring line of windows on the long part of the building.
What I don't like about my composition here is the big grass field on the bottom of the drawing, but any other movement would have broken my already fixed idea for the composition. Also, I did get that tree on the left right in front of the detail on the top of the building...
About light... again, it was a cloudy day, so there weren't any strong shadows. Still light seemed to be coming from in front of me and a little to the right and i've tried to show it both in the building and in the tree to the front.
