Hello Ning. you are very close and your #3 ranking is missing just a little bit.. Change the color of Smart to blue as
#1. Make the Logo a little bigger and bolder. Remove the gray on the circle and just leave it open as
#1 has it. We like your paddleboard person best, but need the rest to blend. Feel free to show a few versions very similar to what you have in your #3 ranked Logo!
