Perplexing
This seems to be a really confusing and perplexing piece to me. It is very greatly drawn but for the most part I can not make heads or tails of what is going on here? The walls, ceiling, and floor all look the same and then the door is front of you just mocking me at how I am unable to tell where I am walking.
The way you shaded all the checkerboards makes this even more confusing to me since I can not seem to tell where to walk either. You did an excellent job with shading here as well which makes me happy though even if it is confusing.
Overall, greatly confusing piece.
