This sounds great. It'd be awesome to hear a full track. Only reason for the 4.5, otherwise I really like this. The highs could possibly be a TINY bit punchier on the chords that start at 0:14 to match the brighter sounds of the leads in the sections before and after, but that's the tiniest little thing I'd change personally.
Otherwise, I love your layering and the way you clearly understand how to piece together some solid and punchy sounding synths. I somehow came across this while looking for stuff relating to Geometry Dash, go figure.
*EDIT* Oh right, I searched Theta and saw a level by a guy named Theta which is what I go by for music, and I have an album called Sequence, so I started tripping out wondering what this was. Come to find a really dope tune, so that's cool! Sequence was the name of my first ambient album way back in 2006 lol I have only like 2 songs from it on here.
