I gave you a 6...
The choice of instrument wasn't too bad, but an accompinament would've worked nicely, maybe some drums and a violin to make it louder and sound better. Some parts weren't the same as the proper song, and sometimes you rushed it too much. It's quite short, so if you tried making it complete, and add more instruments, and slov down then I bet you'd do fine.
