Wait, what is "moombahton".
Anyway this isn't bad.

오.. 엑스트룰러 생각난당,,

I like the combination of Dubstep and Orchestral sounding music. I also liked effects here and there like the choir at 2:00 and your rise back into the main theme. Most people don't have a bridge to their song in the middle like yours. That's a good thing. It really makes you unique. My one suggestion is to add in some small sounds that will grab the listener's attention if they drift away while listening. Sounds like these could include something like occasional finger cymbal dings in the spaces between the harp's melody.
