We like #64 the most from your selection, however we find the logo to resemble a Native-American headdress a bit too much. Can you try that with other colors, like green?
Butterfly is actually a neat idea, but it took us a few seconds here to see it once we knew what it was. Feel free to explore this some more (in ways that maybe slightly less abstract?).
Could you also take something like #59, and try with some other colors, such as green? We just posted a comment on the general board about how think maybe we should be going in that direction. We like those shapes, but it makes it look a bit like a fire, which isn't really "fresh".
