We like a couple of your designs, in particular #56. We had a couple changes we'd be interested in seeing, hopefully they aren't too painful:
1) The "M" capitalized, and the letters in black (and the curved lines in black). The heart and dots, same shading but in a more red tone (darker and lighter reds, instead of darker and lighter pinks).
2) Same changes as in (1), but with the letters on a slightly bigger radius circle....in other words, not quite as curved as it is. Not flat, maybe halfway between flat and the current radius.
