I'm happy you posted how old you are on your page. A lot of us legacy newgrounds users started at a ripe young age too. This totally takes me back to early jam sessions with the bands, friends, and rouges in highschool. It doesn't necessarily have a very polished or professional sound but it's honest and that's what I like about it. I'm practically in tears over here thinking about my old band mates. We would get stoned, hang out, and just make things. Had no idea what those early days meant, we were just scratching our instruments and yowling our songs aloud. It can be hard to pull a full band together but get a percussionist and this could turn into an Explosions In The Sky vibe.
I'd nit pick the shy vocals but it honestly feels really good to hear young unspoiled energy. It almost feels like I'm in the room with you all, I would totally be beat boxing to this. You've got an acoustic sound and another year of highschool? Force one of your friends to start beat boxing right now. It only takes a week to learn how to "BFFF" a good bass drum, "KAH" a good K snare and "TISS" a decent hi hat. Simple 6/8 rock rhythm would go "BFFF, TISS TISS, KAH, TISS TISS" or bassdrum, hi hat, hi hat, snare drum, hi hat, hi hat, then repeat one million times. Look, you don't have to learn how to play the drums. Just force the Asian kid to do it. That Asian kid is going places and you need to make friends with him right now.
