I like the perspective and the way the light is hitting the building. You have a good sense of color! What bugs me a little is that the one cloud is lining up the building, also you might want to work on the trees a little bit more. Depending on wether you want to make this a happy place or not you could use the trees as indicators (make them all twiny and creepy looking haha). Also I'd maybe it might help the composition to set the focal point (the building) a bit off center. The little creek is awesome btw!
Thank you! I'm not done with this in any way (the trees were really half-assed), and your critique will help a lot. It's really rare to find this good critique on this site.
