In my honest opinion...
The original starts out slowly and gradually builds. What you did here was start off with a beat that made no sense to me, and didn't actually get to the song you were remixing until after the first minute. I say get rid of the intro and the little effects, and just basically make a synth pad version of Canon in D. I just don't think this remix does the song justice. Also, make it a bit slower. You have it at what, a little over 120 beats per minute? Make that about 100 beats per minute, it would be better.
Good work though. All that above is my own opinion I guess.
