61, and 62 are very interesting visually -- but I think they might be too much. #60 - what if you were to take away the arch way w/ the blue petals -- just to keep it ultra simple and clean, Also on another version pronounce the wave a little more? keep up the good work!
#72 - please simplify the brush stroke of the wave so. It needs to be produced as formed signage if that helps you. Also would like to see a little cleaner type treatment on the tagline underneath. Please also regulate the kerning of the key logotype a bit. But the logotype treatment overall is good. Thank you!
