There are notable Studio Ghibli films that were not made by Miyazaki such as Grave of the Fireflies, The Tale of the Princess Kaguya and When Marnie was There.
All of those were in my opinion excellent films and similar in style to ones made by Miyazaki, and I think fans of Miyazaki's work will also enjoy them.
I adore "The Secret World of Arrietty" and "When Marnie Was There". I hope Hiromasa Yonebayashi gets to direct more of Ghibli's movies.
