The harmonica needs to be better. The vocals need to be louder. I like the overdubbing or at least it sounds like it was overdubbed on vocals.
I thought this was an okay track. There's alot to be done if you wanna improve it.

The harmonica should be in the correct key.
Nice use of double tracking on the vocals, although I don't it is nessecary. They also need to be louder.
Bass should be louder as well. I think you should also consider using a tighter snare drum.

Here's my stuff if you wanna listen.
