The dreaminess and ethereality definitely comes through. Lydian mode was a great choice, and the 9/8 kept me just a little off kilter in a good way. There's wonderful and creative compositional choices in here, and this would be so so pretty with a live piano track to give some phrasing to those arpeggios and repeated notes.
Also love how you snuck in some "twinkle twinkle" with the celesta :)
