I like the heart. the two colours is more striking, although the 1 colour might be advantageous for print in future...
I like the sense of movement that this logo gives.
It is different, striking - so can be memorable.
I was wondering if there was something we could do with the "milk" drink idea - a splash of white milk? a sense of a carton of milk? do you think there is something that might work in that?
Great working with you
