Taking inspiration from https://www.printables.com/model/476280-the-wandering-tower-die-wandelnden-turme-upgraded-

I added the top part from a different model to make it more cohesive. printed with tree supports.

Also added the crow with a similar aesthetics (still not 100% convinced with the design).

I've added a file that is only the top part. Haven't printed it or test it.
