Nice work! I liked the relaxed, somewhat dark ambient vibe it creates. I like that you developed it very softly.
Constructive feedback: I think it could definitely use more balance on the ears in terms of panning. I would say I might transition to a different chord at 1:37. It also ended up being a little repetitive - which is actually a really common problem when you're sort of "clicking in" the notes. I tend to recommend to everyone to improvise on an instrument, and if you don't have one, at least get a budget midi controller and just mess around with sounds in your DAW.
I actually strangely like the chord at the end quite a bit, and could definitely hear you just doing some drones of those chords, especially since ambient music isn't always asking for much.
Good job!
