its a little on the nose....
A sharper feather would go to my heart, but i like it as it is, i mean I LIKE IT.
I think that this version works better than the other ones, is simple but the concept obviously clear.
the only thing i wud suggest is tht the feather is a bit small compared to the text, i think it shud compliment the text and the logo if seen v small wudnt do tht nd the feather wont show if u see a smaller version of it
I'm not a fan of the symbol. It looks too random, not enough thought through.
Nice and clean design
The mix music-Feather looks good.
The best of your four propositions. It misses only a better colors work to be perfect. Your feathered note is a very good idea.
