Priyanka, Wallpaper on doors is not a good idea. You can go for laminate panelling on the wall and matching laminates on the doors. You can choose a veneer as well. The space is too wide for a single door though. You will have to plan accordingly. I am assuming you are talking about the brown door and not the other black door in picture.

Paint walls and timber ceiling in white. Blue doors and windows are fine as they are, apply topcoat of clear polyurethane for a completed look.
