Pretty cool Isometric 1bit pixel art. Very clean full black or full white approach without any significant dithering. I like how you use the absence of lines where some of the things meet the wall, makes them feel like they are a so smoothly fitted that there is no seam. I like it a little more on the shelf where you omitted the top line aswell, as opposed to the desk where there is no line on the edge but there is one on the top. Also like how you use the negative space to add volume on some of the shapes. The bed railinng and wall clock are the only things that feel a little more one dimensional than my brain would expect them to, everything else feels very solid and grounded in it's space. The only thing that doesnt read well to me is the black line on the far wall above the bed where you placed the hidden signature, it could be a long window but as it doesnt have any depth indicators on the inside it could also just be a long stip of paper or painted wall. But just really minor nit picks, I love it overall.

Thank you so much for sharing. There are definitely a lot of good things one can learn from studying what you did on this piece.
