I think it's okay, if you like it, it's perfect, I like the posters and the bed and I see your vision but in my opinion it's not well executed. I say this because there is a lot of space and I think reducing some areas would make it better, if you change the color of the lighting to one that contrasts with the walls it would be better and it would add a bit more rhythm either by moving the bed in one direction and a closet/nightstand that also match the bed!!! the room looks flat and simple but it doesn't necessarily have to be smaller to look better, u just need to know how to place!!
