I think you'll be okay cuz I don't expect you to make millions of dollars or anything like that. However what would happen if the copyright holders were uptight would be to send you a cease-and-desist letter asking you to stop selling the shirt. If you continued then they might see you. However I suspect you're still okay. I'm not all that familiar with Harry Potter although I do like the movies. What in this design is specific from Harry Potter? For instance is Ravenclaw the house that the weird sisters we're from? In the slogan above what is wit?

The Ramones logo... Its a pretty well known logo and I think some would find it kinda funny. I think to be safe maybe find out who exactly owns the legal rights to the logo and ask permission. It has more to do with the registered trademark (the logo) not the copyright laws. Marky Ramone might see that and be like "wtf?" Its a cool idea but that logo is trademarked and who knows what might happen. Better safe than sorry.
