I'm ashamed to say this when you're so proud of this song but its not quite Touhou 6 until the very end with the trumpets. Zunpets were the huge change that made 6, 7, and 8 so iconic. What this sounds a whole lot like though is Seihou. (If you aren't aware of Seihou, its a bullet hell series ZUN made the music for between the retro and classic windows era.)
I really like the sound of the Seihou songs, but I don't really like the melodies and song structures of most of them. So, the fact that you made one with a good melody and structure is (IMO) the real pride of this song. And don't get the wrong idea about this. Its a good song. I usually hide my scores regardless of what I rate but I'm not in order to emphasize this.
