Thought I'd toss in my 2 cents if you're still open to some feedback 
First of all let me say I thought your performance was amazing! You have a killer voice that packs both resonance and finesse, and a great sense of harmony. The timing on those harmonies is spot on, coming in at just the right times to add impact and taking a back seat to make the performance more intimate, I think you've demonstrated a real knack for when to and when not to harmonize a vocal arrangement.
If I had any criticisms it would be, as Sin and Glyte already mentioned, about the long-winded ending, as I think that by making it almost a minute long you run the risk of having the viewer lose interest and click on another video or something before you have the chance of making your point. Nothing necessarily wrong with the way it was presented, it could've just used a little fat-trimming in my eyes. Also I can't help but feel you're lead vocals lacked a little weight. Not in the sense of your performance (which, again, I loved) but the way it was mixed. It seems as if a lot of the lows and low mids were cut from the lead vocal (or were not in the recording to begin with) but remained present in the backing vocals and the strings, making the lead vocal sound a bit brittle sonically, and also causing them to get kinda buried under the harmonies and the strings when they come in. I don't know if that was an intentional stylistic choice, but it was something that caught my ear.
Keep in mind, though, that these were all just minor nitpicks, something to pad out the message with
Like I said, I think you knocked it out of the park with your performance and I hope you keep doing what your doing. Best of luck in growing your channel!
