Great work on the blues guitar! I'm seriously impressed!
And the songwriting is really good - really strong chorus in particular, I thought, very catchy.
You've a nice voice. Maybe a bit too nice for the blues... but I know you're v young... it still sounds really good. If you could work on getting a harder edge into it, i reckon it'd be even better.
I'm not sure about the doubling of the vocal... and if you got rid of it, you'd also get rid of the difficulty of trying to sync up all the words in both vocals, so it'd sound instantly tidier.
All in all, very impressive writing and performing for someone so young - well, it'd be impressive for someone of any age really - well done!!!
