Yes, Miyazaki's works have definitely been an inspiration to create this, but not specifically Laputa: Castle in the Sky, even though I love the movie. It is more like a general hommage to fantasy worlds, RPGs and the great atmospheres to be found in Ghibli movies, as well as their positive and innocent, bright overall tone. I thought of a concept that will appeal to fans of fantasy, and especially Studio Ghibli, because I've seen a potential there to release a concept album like this. Not entirely a Ghibli fan album, but with a lot of musical nuances in my own style, there are definititely a few stylistic elements in common with Joe Hisaishi's compositions here and there, but also with other atmospheric music I've grown to love during my lifetime. If you consider yourself a fan of Ghibli or fantasy worlds, and atmospheric music, I think it's worth a listen
