This is a pretty solid attempt at isometric pixel art! You did well with the boxy furniture (like the bed, the desk and the drawers), but be careful with more circular shapes, like plant pots. The plant pot on the bedside table, for example, looks very flat, and I highly recommend avoiding the use of dithering over large areas like you did with that plant, since it can be a bit hard on the eyes. Other than that, you did a great job on the piece, keep at it!
