I read from your brief that your company is retail store focus on tennis, golf, and soccer products. Im sure that you want your logo not only talk about tennis, golf, and soccer. But also it must stand alone.
I see similiar thing betwen tennis, golf, and soocer...Thats all can play in grass court... so grass is my main image...when we play tennis, golf, or soccer, we must run in one point to other point to catch a ball. I's very dynamic. Dynamic is grass character too,it can follow the wind blow. I think image of grass is suitable with character of this sport
I use italic font ,because it reflex speed in sport.
I think..that a short description about my art work.I hope you enjoy it
