I don't really like it when people use premade loops in music but you did some original stuff around it. That one loop is from the toxic biohazard, its like the scientist or inventor or something like that. The drum loop is pretty good. This is pretty somber for trance, the only somber trance i can think of is goa trance which is still more upbeat then this. It really just repeats itself and only adds one instrument the whole time.
