Hi Joao, Thank you for your submissions. The one I like best is 47. How about changing the red to more of a tomato red instead of the current red. Also, if you took out the circle and the checkmark and changed the font to something more like Arial, I think it would look really good! Thank you!
Please let me know if you would like to see any changes. The color is the same in all. But that can be refine later. I´m trying 1st to get the logo concept for you.
