Impressive
have you ever considered putting your notes into a program like Fruity Loops? I think you would have so much more power in such a program, as it would allow for more instruments, and more variation. Don't get me wrong, I like these songs as well, it's just a suggestion.
I say that only because I can imagine this wicked violin playing along, but that might be because I love strings too much ;).
4/5 from me this time Mikhail, keep them coming.
