I haven't learned to play an instrument correctly
... so, I hope you find this fair from an inexperienced critic.
Aside from Clocks, I hadn't heard the other two pieces before so, I went ahead and looked them up to compare. You've made good renditions. I think I heard a couple little hiccups in the last two songs but, they weren't major. For not playing for 5 years, I would say that this was impressive.
Improvements? With recording quality, the clearer live music sounds, the better. (Did someone leave a message at 3:02?) Not sure what to use for a piano, tho I know you can use a vocal mic on an acoustic guitar and it will sound great.
I think that if you worked on your speed, maybe? Notes into those predictable sequences at speed would help me recognize the tune... but, you could play it at a slower speed and call it your own because I wouldn't know the difference. :D
You have exposed me to some good music, thanks. 4/5
