Not bad, not bad at all.
Considering of what I've heard of the original, this is a pretty good slow version of the intro. The violins add a sense of depth, and the balance between that and the piano is pretty good.
I think, should you do the whole song as an orchestral like this, with a violin at the lead, it would come out pretty well.
Although, I feel that at 0:19 and 0:35 is where you are weakest. The slow down seems too exaggerated/forced, and the pause felt like you could have cut a second or so off of it and still keep the effect you were striving for.
Still, a nice listen.
Thanks for your comment. I appreciated your explanation it's a real constructive comment which could help me to improve my play :). I just learn piano a few time ago don't know to play it so i'll do this song but little by little :)
