Overall your composition lacks bottom. It feels hollow particularly at the start, and whenever you seemingly randomly decided to drop the bass. You need to keep bass going throughout the whole piece to tie it all together.

Your sample selection is kinda odd. Some of your stuff is high quality, others are synthesized, others are ripped from the original song. If you're remixing, don't use any samples from the original song, cause immediatly you'll be falling back onto the song. You're remixing it, so you have bear in mind that it's your interpretation of how you think the song should sound to you. Your remix as Faw stated, lacks creativity. I'd almost go so far as to say that you replaced the samples and moved the patterns around. Don't get me wrong, around 3:15, the song immediatly becomes much better, mostly because it was the first time in the entire song that it sounded like something new.

Your delay on the orchestra hits, (0:55), is far too much in my opinion. I don't think you should delay on that sample, or if you do, not to do it so overtly.

It was cool sounding, when it was just the original tune and when your original ideas showed through. But overall, tie it together more. Fill the gaps between your ideas and sections. They're not just filler areas you need to make them grow and meaningfully contribute.
