I will give you some feedback!
I like long and constructive feedback so I will give that to you.
One of the things I really liked was that bottle smash, really good job on that sound effect. I also like the underlying music tones at the beginning and the end of the trailer.
Things I didn't care for is how everything sounded very close and could easily tell that all of the sound was recorded in close proximity thus it didn't feel like it was in a space/environment. When the guy gets hit at the beginning I thought it was a punch then was confused of the blood. If it happens to be a punch... great, but if it was supposed to be a stab then we should her some gore of the blade entering the body. The blood effect seemed a little odd to be because it was at a high frequency. Personally, I like blood spurts, gore, etc to sound a little bit lower than water due to the physics that blood is thicker than water. The spray is a little short and could have been a little longer.
Nice helicopter sound, but it seemed to fade far to quickly into the next sequence. Needs a lot more cloth foley type movements, and more harsh wind tones. In real life, if you are directly underneath the skydiver it almost sounds like raging thunder and harsh tone wind.
Needs a lot more foley such as cloth movements and when they are shifting and fighting there way to the location. Good job on the foot steps, guns and the vehicle.
For the night scene... More ambience and foley. Maybe low pass filter on the rain when they are in the building, it seemed empty and quite than automate the change when they are back outside.
The "Drone in position" sounds like it came from call of duty... lol
Basically for the rest, more foley and ambience again.
Make sure to record with a bit of distance, specially with foley.
Remember, reverb and low end are your friends. haha
