Good.
I've played mm2, and i like what you've done with the intro theme.
Only thing keeping this from being jaw drop amazing, inn my opinion, is that, when the music, really kicks inand get fast, you hopefully know what i am referring to, thing is, you use the 'soft' string sound for the slow-mellow parts, that is good, but then you use the same 'soft' stuff for the part when the music is supposed to fill you with the spirit of heroism.
Not sure if i'm making sense. I played mm2 when i was like 6, and i remember when the music got fast it made me feel like getting up and jumping around.
tl;dr: please remake a version using a distorted guitar sound for the fast part. If you made this using reason or some such program, this ought not be too hard.
Wow, sorry for the lengthy review, thanks for reading.
