Few comments about your latest level:
In red: the tiles used could have been any counter tiles. You used the exact tiles as the walls and that can visually confuse players, especially the one above the big window in the middle.
In blue: In the one on the left, its better to have the stairs placed in a continuous manner and the walls crossing over the stairs look a bit confusing unless you are planning to add some sort of glass between them, which will look sick actually!
In green: this didnt make a lof sense to me, since there is already a big table behind it and the area it was put in is very small, just wanted to point that out, nothing major.
Overall I like your creativity with your designs, looks great and its nice how you shaded the floor according to a specific light source! Keep up the good work and I'm looking forward to see more levels from you
