Hmm
The tempo does seem a bit too quickly, and the notes don't flow as soothing as I would expect for such a piece. I youtubed Silent Night to make sure I wasn't crazy, and I'm not. This doesn't seem to have that same calming slow effect that the original we know and love has. I'd suggest re-recording with a much calmer and slower mood.
There seem to be multiple other issues with the recording. Why does one part sound so choppy? Is that you doing that with the instrument? Or is that a recording flaw? I can't tell, but I'm going to assume it was a recording flaw because it doesn't really sound very appropriate for such a song.
Just in the first 8 seconds of the song you can tell a dramatic difference in the way this is played. The first time you hear those notes they sound more bright and have a punch to them. The second time you hear the exact same notes, they sound much better. They flow better and don't have much of a punch to them as they did the first time. That's the kind of style I would expect to hear throughout the whole song.
:10-:12 Sounds choppy and distorted. I'm going to go ahead and guess this was due to some recording issues, but in a song of this manner, it really destroys that calm and peaceful mood with the random seemingly LFO'd sax.
At :16 It sounds like you took a breath, but you didn't fade out the note, so it sounded desperate and not all that soothing. I would definitely work on trying to make everything flow and blend together really nicely for a song like this.
:20-:28 Sounded much to quick as compared to the original.
:30-:37 Didn't really sound in beat to me. It felt like you were jumping around on tempo and just holding notes at different random lengths that didn't necessarily correlate with the original song.
:38-the end Sounded just about perfect, despite the fact that you held one note a bit too long. There's nothing wrong with adding your own twist to a song, but doing a cover of a song like 'Silent Night' that everybody knows, you should try to maintain as close to the song as possible, and only add your own twists here and there, otherwise it's hard to tell what you were attempting to personalize, and what was just simply an amateur mistake.
Overall I think you need to re-record and possibly invest in a better microphone as the recording doesn't seem to sound as crisp and clear as I'd like it to. Mainly the note hold length and tempo was the main downfall, in my opinion. The echo effect you added wasn't overdone at all and probably added a nice full tone to the clips that did sound okay.
Keep at it.
