Oh well, sure ;P
0:08-1:08, 1:28-2:28, 3:51-end => Chord progression's the same as the source chorus's, while flute plays variations from (but intends to focus) the source melody, as does bouzouki (greek instrument that sounds sitar-ish). The intro theme may have a somewhat difficult melody to comprehend, but, take the chorus or 0:56-1:08 (from my ReMix) as an example, so I think you might recognize the rest.
1:12-1:24, 2:32-2:44, 3:36-3:48 => Chord progression's from the middle part from source (as is the piano), and
2:48-3:35 => Everything's original.
Many thanks for the feedback, guys! I might visit India again someday; by now, I'll keep touring different countries, as I'd like to try many rhythms as possible.
Also, is the title okay for ya? Should I rename it to something easier to read (and say)?
