You've got a good idea, here and I can see what it is you've tried to do.
You've gone for a mix between electro and Asian music, to stick with the theme, right?
Strictly on a musical basis, I feel like there's a lot of room for improvement here.
The melody sounds much more appropriate for something like Castlevania, rather than an Asian swordsman. I'd suggest listening to some classical Asian music and making a melody that focuses on more eastern keys.
There's a huge opportunity to add some real depth to this piece with some really classic oriental sounds. There's a beautiful kind of juxtaposition between classical instruments and modern synthesiser sounds I find. The flute is a good start, but you can use some instruments like the shamisen and koto. Also, don't be afraid to use some Asian percussive sounds like gongs. They're a great way to bridge the gap into a drop.
On that note, too. It seems like there wasn't really a flow to your piece. You can tell you knew what you wanted in the music, but there isn't really a structure, or narrative if you will. In techno music the usual structure is light beginning, melody introduced, build up, drop, heavy beat, light beat with melody ontop, interlude, build up, drop, ending.
The entire time I was listening to this, I was craving a really good bass line but I never really got it. Bass lines are a key component of electro music, and I know for sure a good bass line will make this song much better.
One last note, try not to loop the same melody over and over. It can get quite boring for listeners to hear the same melody repeated for several bars in a row. Decide on a key melody. Which is usually your chorus, and make that the big one. Then create some more simple melodies for the other parts.
All that aside, this is a quality piece of music and you've got some great sounds.
