This is such a great song, hard to sing, musically it has a tricky bit in it, so you definitely need to stretch in a couple of ways Buddy!
So what do I think
.....:
Adding the cajon and tambourine is of course really great, the song is really based on rhythm!
And Willem is right, the pitch in the chorus isn't quite right. It's indeed a stretch! :S Lower it a half step and you should be fine.
Musically, actually....for example, most of the chordchanges in the verses are on the 'and' of 1, so nót on the first beat. You can play it as you do, it's fine, many people do, but it would be really cool to add it since it really is recorded that way, I think it's pretty cool and way more interesting and of course accurate! B)
Also, it would be cool to play the song with powerchords. The link above is of a very small performance of this song, starting at 10.11, you can hear and see the guitarplayer very well in that. Check it out, it's really a very great mini-concert!
Other than that, since this isn't just audio, but also video, I would soooooooo much like you to actually 'perform' a song, instead of standing sideways, staring at, I suppose, the lyrics. It's like watching a robot, with little movements with two hands. Again if this is just audio, who cares, but there ís an audience watching too......I'm only mentioning this, since you've come a long way Buddy, you're só into singing, playing, recording, you got a lot to share, which you do. You have tons of videos on your channel, so improvement in that direction would be a good one and also one that you should be able to handle by now. I know you áre always looking for improvement......so.....anyway, I mean well by it...
So, that's what I think...
cheers!
