Hans,
First of all, very good tune. I like progression, choice of instruments and vocals!

I might be not the right guy to professionally comment, so consider this is as a honest opinion of average listener. It seems to me that vocals are a bit detached from main backing track. Feels like it resides in high frequency than the rest and a bit loud. I would try fool around with trying to blend vocals better in the mix.

Thank you for posting,

Misha.
