Outstanding! Keep it up is all I can say.
I was in my first band when I was 12-13 years old and it was some of the most fun I've ever had. We only played a few paying gigs, but it felt so rewarding to actually make money from playing music instead of our part-time jobs (delivering newspapers, etc.). We even got to play a concert at our school dance (in between the breaks of the cover band the school hired) and we became quite popular locally.
We mostly played covers of the hard rock bands of the time (Deep Purple, Uriah Heep, Black Sabbath, Nazareth, etc.), but we also wrote a few of our own tunes. Have you guys tried writing anything yet?
Hope things go your way and you guys can stick together at least until high school. Our drummer was in a really bad motorcycle accident 3 years after we formed the band and couldn't play anymore. Needless to say it was never quite the same after that, even though his replacement was a better drummer.
