The busy beat at the beginning was...interesting, to say the least. The transition at :22 felt a little rough, and I agree that the snare that comes in at :45 is a little strange. I have to say, though, I love how it was relaxed, yet climactic. The melody is really engaging and the effects you have in there add a lot to the piece. It did get a little repetitive, but the ambient nature of it makes up for that. Personally, I don't like fade-out endings, but I really felt the melody and the beat. I can't believe you're only 15! You have a bright future in front of you, my friend. :D
