If it's the best you could then it's enough to make me spend some nice 3'43"
seems you've a nice instrument and you deserve it by the playing.
Could not find a flaw on the artistic choices, and you're better than me for that playing stuff.
dont know the original, but liked your version anyhow

return of critique would be enjoyed :
That's amazing man! I'm currently working on this song myself. I guess i do pretty well for now xD! Do you work with a metronome? I find it very hard to use a metronome. I probably use it very wrong.
