I cant make out the vocals enough during the verse for this type tune, also ( big harmonies during the chorus would be nice.) Not to beat a dead horse, but there are better strings avail, without breaking the bank. they do sound dated.
I think you've got a good chorus there, but I would emphasize it a lot more. Bring back the instruments during the verses so the vocal comes through and theres a bigger contrast between the vrs & chrs.
Its good work, but I think you can make it better.
