Hey, wow, this is actually very neat Great choice of source, you used it very well in your remix too. Generally, I love your arrangement - the transition from ambient chillout groove to hard rock feels a lot more natural in action than it sounds on paper, so good job for making that work!
To be honest, starting off the song with these weak harp samples isn't doing you any favors; the rest of your sounds throughout the remix are pretty high quality and expressive, but the harp sounds like something I'd expect out of a general MIDI soundfont I was ready to write off the mix before it really even started, and I'm guessing other listeners might feel the same, so see if you can hook yourself up with some higher-quality harp sounds.
The Youtube mirror isn't doing your song any favors, but listening on soundcloud is definitely recommended for anyone viewing this thread There's still some compression issues on the drums, like Guifrog stated, and I think you should consider toning down the rhythm guitars in the second section so your lead synth can have a little more room to stand out. Otherwise, it's pretty good on the production end of things.
Very good arrangement though and a great listen, I'm pleasantly surprised to see a good DKL source get some love! I hope you take the time to polish this up in a few places, hopefully it'll be OCR-ready with very little effort!
