Big boy rooms

Hey everyone! Looking for some inspiration as we start moving around rooms and furniture. My son went from a sports themed nursery to a Mickey Mouse themed toddler room in a full size bed. We’re going to move the full size to my toddler daughter and give my son the queen so wanting to update his room to marvel/Spider-Man but in a classy way that will last a while. I’m thinking themed wall art and sheets with a solid gray quilt or comforter.
