I could make the same comments as everyone on your voice, but instead I'm going to put some positive to it. I like you're voice, the timbre fits the song, in my opinion. Sometimes intonation is off, but that's all fine muscle control that comes with practice. Vocalists sing for years to get that control. I personally sing things over and over just to get it even close to being in tune.
Secondly, you're placement of the words in rhythm is good. The way you stretched some things really worked nicely, and I liked that a lot. You're also very clear, something that is hard for me personally, so kudos on that.
Guitar work is awesome. I can't say much else about that.
Overall, I like it.
