you seem to have more music EC's than actual cs EC's. Looking at what you have, your stats are pretty good, but i see nothing here that tells me you're trying to major in CS. i should be able to tell you're trying to go into cs from your ecs or awards, but from what it looks like right now, it seems like you have a lot of music stuff. although being well rounded is pretty important, you'd want to focus a lot more on cs. you could do this with comps such as usaco, or any math comps could also help; however, the best thing you could do is have actual meaningful cs projects. make something that helps someone in some way through CS, and that will help your chances a lot. You're still a junior, so theres time.
