Hi! I think it looks cool, I like the photos and the wall paper texture. There are a few problems though, IMO, most notably the ever present "what is solid terrain" issue that you always struggle with when making a platformer. For example, are the books something you'll collide with? The book shelf? What I after a while realized was a window I at first thought was a big block of solid terrain, as it shares the feature of being dark with the walls.
The most common way to tackle this is to make the foreground a different colour tint than the background, and make the background more faded contrast- and saturation-wise. In most of the cases people tend to make the foreground warmer colors (yellower) and the background colder colors (bluer):
Another thing: The sense of scale in this screenshot seems a lot different~
If I were to imagine the size of a bed based on those graphics, I'd say it would occupy no more than one tile. What's up with that?
Anyway, you've obviously done pixel art before, so I think you'll find your way with this. And it'll be really interesting to see where you take your crazy moving room idea
