Your lead in the opening is really bright, loud and consistent. I would enjoy more playing around with its timbre and register. Pads are a bit on the blandish side.
That synth strings build towards the end needs something more. More presence, maybe something small moving in the background, but all alone it sort of falls flat.
Bass could use a tiny bit more presence.
A little bit more variation in the piano arpeggios (occasional switch ups, syncopations, fun panning) would be excellent additions.
Good luck, you have a pretty solid base here.
