I would like the logo to have one or more tennis elements (a tennis court, a raquet, a tennis ball, or even a person doing a tennis shot position, you name it). Also combine social network elements such as comment balloons, arrows, etc.
KEEP IT SIMPLE. CLASSY, EYE CANDY, MINIMALIST, MODERN
Keep in mind the most common colors found in tennis: white, gray, light blue, light green, dark blue, dark green, etc.
I do like shadows and gradients
Please avoid the user of pink, purple, orange, or tennis stuff that can look old.
