you would have to trust him on the mastering though your songs are great but just like me in the same phase of my audio tool experience the mastering has a way to go yet :) you should hear some of my old stuff and you will know what i mean compared to my new stuff lol
i would fav for the pic alone hehe - the track is cool you're delving into solid territory where less is more... keep experimenting it's a very cool track your bass is well-integrated and the other elements spell talent so i would nix the opening comment because you're doing great !
