I think the angled bed is a good idea for a topdown game, gives the room a sense of depth it otherwise might not have. Maybe less so if it's a sidescroller, but if you're just interested in passable work this can easily do it for now.
If you want some crits: the dressers are too flat, from that angle you'd see more of the tops of them. The window/poster is just a blank orange square, curtains, a pattern, or a window sill might make it clearer. The rug is a great design, it contrasts well with the protagonist walking on it, but it might help to layer floor under it to better gauge how it works as a whole, i'd try woods of various types for that.
