other than that id say if you want it to sound more like a standalone track, make it longer and add more variety. as it is, it sounds like a short interlude in an album maybe, which is totally fine if thats what you intended! it actually works very nice as that :)
this is really cool as it is! one thing you could do though is split off the lead synth to another signal that has a lot lot lot of stereo reverb and a high resonance lowpass that you could increase throughout the entire thing, so it would start out sounding how it does now but gradually more and more color might come through.
