I obviously like #74 a lot. I have had a few comments from friends that it is a little too "swan like". Could you maybe try one where it is a more traditional music note shape. Possibly try facing the other direction as well.
Thank you for the great feedback! I have submitted some changes in #74. see #155 #156 #157 #158. If you have some other suggestions, I'd be happy to make revisions.
Could you try reversing the music note on #161. I think keeping the music note in the standard direction is probably better than having it resemble the letter b.
