Wow, are you sure you aren't like 35? Your voice is so mature. (and sexy, if I do say so myself, but that's not the kind of feedback you were looking for

) But seriously, you have one of the best high school aged voices I have ever heard. If I didn't know you were 17, I would have thought that that was one of the Broadway Val Jeans.
But for some constructive critisim, I agree with the others, Bring Him Home started a little too strong with too much vibrato. Tone it down a bit and it'll be perfect. And I hear strain on the higher notes, but since you said you are a baritone, it's all good.
Good luck with Interlochen! I would kill to go there for the rest of my high school years.
