Hi Anna,
Thanks so much for your great submissions. I definitely like #40 the best, as for the concept, but I like the simplicity of #41 as well. I am looking something a bit more sleek and simple, as far as the font and overall design is concerned. One of the primary things I want to convey through the logo is "purity," so I'd like to use a font that is very clean and lightweight.
Thank you! ~Daniela
