A very good tune overall. I'd say it's flawless if not for the A note at 0:21-0:23. I don't know if it was intentional, but it came off too strong and vibrant and out of key. When the same A shows up again at 0:30, it sounds much better placed.
No problem, man, I'm no professional myself, I'm still learning, and certainly I agree with you on the masterpiece of the original song, I could personally play it for hours and not get tired of it. To add some more info, I really did like when you brought the percussion stuff in, it came in at the beginning there and I was like, "Ooooo." Lol I think this has some pretty good potential.
