Ummm........ Titanic?

Sorry but this doesn't really sound like it was supposed to be a Titanic song remix. I could tell very little that it was supposed to be "My Heart Will Go On". If the notes for the melody weren't broken up, I think it would have been better. Points for effort though.

its lacking punch or real inspiration

When I started listening to this, after a few bars I thought it was 'Amazing Grace' or Rabbie Burns' 'Should Auld Aquantance be forgot'. For some reason. (This was on the NGAP Radio, where I didn't see the name.)

It's a fairly simple but effetive technique - replaying the melody using those vibrating instruments, then adding some beats. It sounded good, but yet a bit more could have been done - sometimes the modulation sorta times well with the beat or makes an extra rhythm of its own. Maybe you could've made mor of that?

Or maybe added some more layers etc?

It was fine to listen to, but just kinda sounds like its lacking punch or real inspiration at the minute.
