I really like design #26 for its simplicity and bold graphic quality. You've balanced the idea of natural without making it too fluffy. The shade of purple you've selected works well and I'd like to see it in other colors as well. I'm glad you followed up on my hint to try the Buddhist circle. The quality is a bit to light for what I was hoping for. Is it possible to do a thick circle (something like this- http://www.tumblr.com/tagged/enso- or the lower left-hand corner of those found here- http://www.vanishingtattoo.com/tds/tattoos_designs_symbols_buddha_zen_circle_inspiration.htm) and cut across it with a bold font to create some tension?
