Haven't been up here in awhile but here is my 2cents.
Overall it's great, I think I might have adjusted one of the doors like callimuc was saying. What i did was shift the whole thing to the right and added in the /side/ of the door as it would be visible from the slanted angle along with darkened it. Suggesting the light is coming from the /left,top/.
Your bricks look good if everything else matches them, but I went ahead and added another option for the bottom. I don't have the time to accent all the red bricks like I would like to.
Lastly I removed the outline separating the 2 sections of brick from each other. As the middle sticks out it should cash some sort of shadow on objects to the right.
Added some sort of balcony support and made the shadow even all the way across. Even though the depth of wall changes the balcony casting the shadow dose not, so no real need to have uneven shadows.
