Stating that you haven't added overdrive yet and that it is unfinished indicates that the song is in early stages and you're unlikely to get much response unless someone loves the song. Also. the song you chose to start with is obscure so no response is what I would expect. (sorry if that is blunt.)
Here's just a bit of advice. I'd recommend that you finish your song as completely as you can and then add it to the customs database. The more complete you make it, the better people will respond, or least download. Add the overdrives, practice sections, all instruments, expert + CAT at least, but preferably full reductions. The reason I stress full reductions is that the process of doing reductions by hand will almost always reveal flaws in your expert charts and result in higher quality charts.
Don't let the lack of response stop you. You can put out complete songs and very few people will take the time to respond or say thanks. That's OK if your primary motivation is for yourself.
