I don't know...I'm not really liking a lot of the OST so far. In Original 1, there's a harsh pitch bend at the end of pattern 01 and another at pattern 06 which carries over into the next loop. And the tune isn't fast-paced enough for a level. On the other hand, I'd imagine it would work well for a cutscene with some sort of an oriental-themed character (like how Kalinka was Russian).

Original 2 starts off very well. Frames 00-02 don't song very Megaman-ish at all, but I think they're good as-is. But after that, the song falls into a repetitive main chorus.

Original 3 has a good baseline, but again, the chorus is repetitive and sounds too harsh for a level theme. Personally, I think stage themes should fall into the category of upbeat (Magnet Man), edgy (Solar Man) or epic (Tank Man). But this theme doesn't really fall into any of those categories, so I think it'd work best for a cutscene (like a kidnapping or invasion)

Overall, you have a really good grip on your instruments and baseline, but your leads aren't catchy or strong enough to hold their own. Listening to this OST, I get the impression that you're really experienced with Famitracker...but not with composing original music. Try improving in that area by listening to other modules and seeing how people form their leads!

Good luck, man.
