I like the sounds you picked, and how it fits the vibe. Sounds like its Dune inspired.
I'd say the mix is a little dry and narrow. It sounds like the sound that I'd want to be big and wide (the main sound) is like a small thing in front of my face, rather than big and filling the space.
I'd apply a realistic reverb and pump the space up.
I left you a message in the discord server.
Great work! :)
