Nice drawing! I've heard about Prince of Tennis, but I haven't watched it. I haven't really been into anime about sports. The only sports anime I tried was Hajime no ippo, but I stopped watching it because I was busy around the time and I didn't get back to it.

But Prince of Tennis has some really good reviews though, so I may need to give it a try.

Keep up the good work! And here's a high five to you!
