None of your ideas are bad, but I think the quality of synths is doing your arrangement a disservice.

Let me pause to explain what I mean as I realize that's vague. I think you need more instruments and contrast of instruments. Something besides the bare leads. Pads, clear bassline, etc. A little study of songwriting and arrangement will do you a lot of good in this area. And don't feel like you absolutely must create every single sound you use, down to the waveform. Some samples are perfectly okay as long as they are royalty free.

I run into the same issue you have in this track a lot, in that the rest of the instrumentation is pretty bare, so I completely rely on the lead to carry the track the whole way through. It gets so complex, so busy, that even my best lead lines go unnoticed.

Also never underestimate the power of offbeats and weak beats. Not every melody must start on a downbeat

Back to arrangement

It's quite busy and there seems to be an ambivalence in terms of structure. I would like to see more of this kind of ambition, especially the final big section, with just a little more structural finesse! You're getting there!
