Weak EC's?

Hey guys, I am a rising Junior and I just realized that my EC’s are quite weak. I feel like I do not have enough variety. Do you guys have any suggestions about what type of EC’s colleges are looking for? I am Asian, so I don’t want to be too stereotypical. Also, I am absolutely NOT interested in Science or Math so please no medical internship/program suggestions!! My high school is the best in the state. I am definitely more of a humanities person with an interest in government policy and history. Here are my current EC’s:

-Speech and Debate Team(this takes up a LOT of time. Practices are everyday after school so it has really limited what types of activities I can do…but I am really involved with the team. So far I’ve gone to two summer camps just for debate)
-Volunteer at the Magic House
-Piano(State Champion-Solo(9), 2x State champion in Duet(9,10), 2x Honorable Mention in a prestigious city competition(9,10), and won a Piano Concerto Competition(10, will play with the orchestra in April)
-DECA(10). First at Regionals and finalist at State(I can’t do this next year because of schedule problems)

Is this too little?? My parents tell me that I am not doing enough, but honestly I don’t know how I will be able to fit in other activities especially in Junior year with a very rigorous schedule. I just don’t understand how some people can do it without losing focus on their courses! I feel like these are too typical of the EC’s colleges see from students. Help??

I forgot to mention, I also did an International Public Policy Forum Debate Contest(didn’t win anything, so I don’t know if this is worthy to put on the application)
