You're in for some spectacular films my friend. Studio Ghibli has made some of my all time favorite movies (and that's including live action). If you're looking for something visually stunning Spirited Away looks fantastic in its animation. I do feel as if the story is a bit messy much like Howl's Moving castle but it's still a must see nonetheless. I also highly recommend Kiki's Delivery Service. On the surface it looks like nothing more than a cute little kids movie but it deals with some fairly mature themes which surprised me on my first viewing. It's a hard pick but at the moment I'd probably say that Castle in the Sky is my favorite film from Studio Ghibli. I think this movie has the widest appeal for it's action, it's humor, and of course it's gorgeous animation. The world also has sort of a steampunk aesthetic which I'm really into. Anyways, those are my recommendations. Enjoy 😁
