So, you have the right idea with this intro but the lead is too loud and too in your face so when you finally get to the drop it doesn't have the same impact. You could either put a filter on that lead during the intro or you could add a break down before the first drop. Also, widen that lead up. Also, however catchy your melody is, people get bored after a few minutes. Dont be afraid to change it up and have fun. Mix wise it needs a lot of work because all I can hear now is the kick and lead and Im losing some of those awesome chords in the background.

I agree with ELD about the intro lead being too prominent. The second drop sounds much more powerful, and it's really cool in my opinion.

For the middle part, I would try to add another, slower-evolving melody, with a higher-pitched lead/string sound for example. The piano could be in the background and build up in volume. That way it would sound less repetitive yet still coherent.

Also, you could try to adjust the volumes of the piano notes to make them more realistic (the repeated notes sound a bit machine-guney).
