How much of a turnoff is it if a man's room is full of things he likes?

21M here and I'm in university. I unfortunately live with my mom and step dad (dad unfortunately passed away last December).

I love my room. It's filled with movie posters of my favorite movies such as spiderman 2, Rocky, and Scream. These posters along with 8x10 prints on my wall have all been signed by the actors that appeared in these movies and tv shows. For example I have a scream poster signed by a majority of the cast, I have an 8x10 photo signed by Giancarlo Esposito (Gus Fringe from Breaking Bad'), a "pawtagraph" of the dog from Deadpool 3, etc.

Aside from these prints, I have my basketball jersey framed and put on my wall, some funkos, and a bookshelf filled with books and graphic novels.

I love my room and I think it looks great. However I'm insecure as if I somehow do have a woman over she's gonna think I'm a nerd or a little child and not want anything to do with me after.

If you were in this hypothetical situation would you be turned off?
