Hi Olga,
I am very glad that you like the design.
Here is the revision as you suggested: #16
The idea of the icon is the 3 lines that are used for a eye brow waxing technique inside a sphere that also represent the letter "O". Also I have used another font treatment, let me know witch one you like more.
Hope you like the idea and if you have any suggestions please feel free to let me know
Comments appreciated
Thank you!
