That looks great. Very photorealistic, while still maintaining some contour line-drawing charm. The treatment of all the glass reflections is nuts. I assume you were working from photo reference, but if not, awesome job catching details like the shadows cast from the fence onto the door (awesome job even if you were to including them). The distorted reflections are great too.
How did you do it? The building lines look really clean like they were done in Illustrator, but stuff like the tree branches look freehand.
