<p>I don’t think your list looks too bad. My D’s list was actually somewhat like yours, except she did Quiz Bowl in depth (vs. marching band). That is okay, especially because your Color Guard team did well! I would recommend you try some fencing competitions. My D club fenced for years without going to competitions. She finally tried competition her senior year and finished fifth in the state in her weapon in only her second tournament! Which made a nice mid-year email to the admissions offices as an addition to her applications. 
She got into U of Chicago, Swarthmore, and Harvey Mudd, along with several other schools (others with quite a bit of merit aid, too). I think you are fine, just keep doing what you are doing.</p>
<p>One thing to consider is how you will spend your summer after junior year – if you can find something productive to do related to any of your ECs, that is something to consider.</p>
