Hi again Joanne,
you might pay a little attention to the sibilance in your lead vocal - since it's more "up front" and crisp - a gentle treatment with a De-Esser might be worth testing. (I've listened to your song on my Sennheiser HD25 Alu + the speakers in my car)
The song keep growing on me every time I listen to it - it's is really quality work from start to finish.
Cheers
Peter
