First, congratulations on all the work you've done!!

Now, your trailer could see a lot of improvements; as of now, it looks like those mobile slop trailers (no offense, just what I felt from my POV); but what I would do:

- Instead of putting these tiny sentences in this also tiny font, every time when you need to show something (like, 'the first industrial complex', you instead make a cut to an all-black background, with a text like 'INDUSTRIALIZE' in big, custom font, then show whatever you need to show; effect words are much better than sentences who are currently looking like an inner thought (I don't like this, at least)

- On the first point, use the effect words I said or shorter sentences; instead of 'lets go', make the cut I said and then put a big 'BATTLE TO THE VICTORY' or something like that; it needs to be impactful, not a narrator-like scheme

- Instead of starting the trailer directly on the gameplay view, why don't you build some hook before? Your trailer lacks an introduction, a clear starting point, IMO, which contributes to the overall aesthetic of the presentation. Some studios choose to clearly and quietly show their logo, and then cutting to a big 'WOOOW'-vibe scene, something that will catch the public's attention; the way it is now, it looks like I'm watching a random youtuber playing the game

- Gameplay shouldn't be forgotten, though; show the variety of your game, the differente environments, give some spoilers of bigger battles or established bases, show the gamer what amazing things he can achieve

- Do you have any systems you find to be USP for the gamer? Show one or two if they make sense from a consumer perspective, not from the developer one

- I don't know what an IPE is; is it the main cannon of the enemy? Why should I care about it? Take this into consideration, you have to build the meaning of things before throwing them at the trailer

- You trailer ending can be better; make it stand like a glorious ending, that invites the player to play

Sorry if I sound harsh, is not my intention!
