Here is my suggestion to you my friend.
Machinima is a tricky business, before you even consider filming and action machinima look at other great machinimas.
Watch how the angles are changed and the camera moves at a steady pace, never jerking around.
Story lines can still be told without words, you can still tell what is going on with this video.
Always have a story or else the viewer doesn't know what to expect or look for, because the viewer wants to make conclusions and guess what is going to happen.
I am not sure if you were going for the cloverfield camera, but don't just follow the same guy around, keep the angles interesting and fresh.
Filming takes A LOT of time. You need to be patient.
Filming something like that and doing it right, would take 8-9 hours.
Good luck man! You need to learn and gather knowledge from others!
