I really appreciate you giving me so many different styles here to look at.
I started looking at #5 again. Based on some of the notes I expressed in my brief and other messages for the contest, do you think you could take another stab with the symbol of #5...but see if you can make it softer and more relaxing? In this version of #5 the symbol feels a little harsh.
Would love to see what else you might be able to come up with!
