I felt obliged...
...To write this review, this was for me a very... Interesting thing to listen.
Personally I don't like pop songs, or anything with an acoustic guitar, but the song managed to keep my attention, mainly the lyrics.
The lyrics themselves were pretty much too soft for me, when I first listened, but then they started to make sense and the song had my full attention again, well chosen.
Then your part in this:
You can sing very well, let me tell you that. I had to get used to your voice at first, but that can also be because you sing the sing a bit higher than I'm used to (with other songs).
I'm assuming it's you who's playing the guitar and I also think good job at that. I've never played the acoustic guitar in my life (I've played electric baseguitar for a while), but I've always found it very hard to play it; respect for doing that AND singing at the same time. Nowadays this doesn't seem much, but you did it and you did it right.
Sidenote: how well is the quality of your recording mic? It's perhaps a good idea to invest in a better one.
Overall I'd give a 6/10 for the song chosen for the cover and an 8/10 for the cover, so in total that'd make a 7/10 and a 4/5, well done.
(I'm counting the cover heavier, but rounding that up would still make a 7/10 average).
Keep it up!
