If you don’t mind a little design critic I would make the steeple larger, possible more square shaped versus rectangular. Its sort of the focal point of any church so you want the player to recognize it as such right away. I’d push out the entrance and make that a little more ornate as well. If you’re entering a house of god it should maybe feel like a shift from the outside world.
On the other hand if you’re going for a dusty, downtrodden and underused church vibe you are right on the money at the moment.
Just my 2 cents!
