Okay its decent matinee, not the best, but considering you used stock assets there's really not many degrees of freedom. But I don't understand the narrative that it seems your trying to weave together with these montages. So, let me try here (calling that pensive guy holding that object the protagonist):
It starts out with a pensive protagonist sitting in front of a building (0:07-0:30)
Two units infiltrate the compound (0:32-0:34)
The two units approach the same building the protagonist was sitting in front off (the audience learns that the protagonist and the antagonist occupy the same space now, but are not yet sure if time differences are at play here) (0:44-0:47)
The protagonist stands up (0:59) but why?
The infiltrators throw a grenade at some units (1:02). Are those units on the same side as the protagonist?
(1:06-1:19) What is the protagonist doing? It seems he is the guardian of the building ie defending it but despite missing the infiltrators (which at this point seems to be occurring in a different time frame) he senses danger and so feels the need to stand up and position himself atop the stairs?
I really don't understand the relationship between any of these characters. Cool matinee, but the narrative here is downright confusing.
Thanks for your feedback I believe what you didn´t understand is that one of the infiltrators is the protagonist, who is holding his fallen mate´s armour. He is just remembering what just happened.
I wanted to override the color of the infiltration sequences, to enphaseze the flashback feeling... but I couldnt get it work so... too bad on my side. If you have another look to the vidoe, you´ll see it has more sense now
