Oh my god, you don't know how happy I was to see this! You know, a while back I had to create a utopia for school and this looks so much like what I had imagined (the floating main city was where a large symbol of my utopia should be where things are branched to it like what you have here).
This is beautiful! The landscaping and everything was just so similar, it brought me back to my Utopia called Aether, the Ethereal Sanctuary.
God I love all of your art haha. Love the primitives XD
