Does taking two off-blocks senior year look bad for top colleges (i.e. HYPSM+)

What about art or music classes? Our high school requires two classes along with two business classes, three PE/Health. I think showing some interest in the arts/music/business is only a good thing. I love the idea of being an asst for a teacher. Enjoy your senior year, you already have a really hard schedule. My son has 11 AP classes yet he has taken handbells, art, plus about 5-6 other electives.
