Howdy Mir,
I only assumed with the video that you were going for the movie soundtrack thing. It could also be a song for sure.
Your mention of 'middle lows' is telling me your monitoring or room treatment is not good. I hear a bit to much low mid in my studio.
I am hearing a lack of sub frequencies, high frequencies and a buildup around 250hz.
I am curious and bored. What software are you using? Can you send me individual tracks without effects?
Much more to ask...
