This is a piece that I created with ShinsukeIto. It was actually made before Sweetly Scented Celandine. We took turns doing each section and I was supposed to add guitar, but then I ended up not being happy with it and procrastinating for months. But finally it's done (halfway into the next collaboration with him).
You are welcome to use this in your work (no need to PM me since I reply really slow) though I'd appreciate if you linked to this page (and showed me the finished work!).
