Okay , here's my thought....I like the first colors best. I would change the way the "love you" is placed. I would make it a little smaller and put it in the lighter section in the center of the heart. The "love" moving down from left to right, the "you" moving up on the other side. I think it would look more like part of the design then something added as an afterthought......Just my thought!
I envy you getting to spend all that time in Hawaii! I hope you have a blast! :D :D :D
