Keep it up yo! If you want some unsolicited advice, I'd say to write songs faster! About a year ago I started writing on average a song a week, and I've noticed my quality really improve after I made that decision.
Here's some guy who backs me up on this: http://www.codinghorror.com/blog/2008/08/quantity-always-trumps-quality.html
Also like BlueOceans said you write good reviews. You are way more observant than I was when I was your age. That can only be a good thing!

Good Luck with your future songs! You deserve all those core supporters since you spent so much time reviewing other peoeple's songs with a lot of detail.
I don't think it would work very well since our taste in music is so different, but I would like to try a collab. One of us can make the main melody/ies, and the other one can make the actual song using that melody.

Thanks BlueOceans! :D About the collab, I actually wasn't referring to you, but I'd love to make a collab with you if I have the time! :) During a vacation is probably the best time for me...Thanksgiving or late December or whenever. ;)
