looking very nice, i like it a lot!
since you wanted some critism:
1. the opened doors are kinda bothering me, cant really tell why. i guess its the way you've been rotating them (ps: also the glass is missing the lighter gray shadow)?
2. the very left and right wooden end of the balcony should also get like a dark border, so it doesnt just look cut off. Or anything else symbolizing its end (for the wooden part)
3. and the last thing which could be improved is the shadow below the balcony (im not too sure though about that). wouldnt the shadow need to be less high on the wall which is more to the front and vice versa for the one in the back? like this:
im not too sure though, probably also depends on how the "sun" is
