Awesome
You have some really good shots, and timing. Your smoke effects are really nice too.
I didn't see too many inconstancies. It was really solid. Some of the walk/ run cycles are weightless. Focus on getting the recoil.
I seen you had a top down 3/4 shot in the beginning in perspective of the character walking in the room. Leave it for now the project is complete, but look at that shot for where you could improve. If you want me to point out what it should look like I could draw over your keys. I'm sure you can have an instructor look over it.
I don't like the chasm jump. It feels faked, like you didn't act it out or you hit the mid-project jitters. Everything else, especially the beginning was top notch.
One last thing, don't apologize in advance. There is always some problems or things you'd like to add but have to meet the deadline. Just throw the work out there and let the audience decide. You'd be surprised how much they never notice. Even other animators let stuff slide if the finished product is good.
