This drawing is from a room in one point perspective, but it is made so the viewer can't really know what the ground really is. I like the depth the perspective gives to the room. I like how the shelves are a form, how they occupy space and look like they have mass.  I don't like how small the scenery in the middle wall/floor looks, I would like it to be a bit bigger. I also like the texture of the walls and floors.
