Filesize doesn't matter that much in cinematics, as long as all files have been used in an optimal way (I've seen cinematics where the authors did import music, but never played it for example).
The description inspired me to watch the entire cinematic and give some comments on it, let's hope you read all of it since I rarely review a map and always spend a lot of time on it.
(People can really learn from that description by the way, congratulations!)
The unprotection is also a great thing in my opinion.
You have imported quite a lot of awesome models and put them to good use, but "the ultimate terraining map" is not valid for credits and neither have you given credits in-game, which you really should.
The music was also put to a good use and was a great help to build up the atmosphere (though you should probably note which song it is, apart from the original author).
The terrain was also heavily based on said models (and skins), but I find it hard to judge that because creating a samurai town with standard warcraft models would be near impossible.
Then again: try to work a little on some of the doodads placed and the tileset, I could only see 1 fog (might be mistaken there), you can change this in-game to change the atmosphere even further.
Besides that, there were awfully much typo's and grammatical errors, which could've been prevented with the use of a simple spelling checker (copy/paste it in MS word or something).
Also, try not to overuse the triple-point ('...'), use an exclamation mark or any other fitting symbol where due (such as "No, no, no, no this can't be happening...", you can put an exclamation mark at the end).
At first, I thought the dialogues were rather good (if you neglect the mistakes), but they quickly turned out to be standard Americanized dialogues.
You started repeating "honour" over and over, making it a bit boring and then it turned out to sentences like
"Just shut up, and keep fighting!!",
"What the hell?" or
"Arghh! Shit! There's so many of them!" (literally taken from the cinematic) and I really though OH, COME ON! You started out so well with the introduction and then you do stuff like that?
Most of the battles were a complete mess... most of the time some random fighting and I can't see why there would be a burning tree when there are people fighting with katanas and swords (even the gunpowder units don't just burn a tree, they either blow it away or put a hole in it).
Then there's the blight in the central room, how can there be blight there?
The triggers are also pretty messy: no leaks removed, waits instead of a timer, no real movement system (apart from Paladon's systems).
The bullet doesn't even fly straight, it would've been very entertaining if you actually used a movement system and decent camera-work for the bullet (not too matrix-styled, but not too passive either).
The camerawork is avarage: the movements were good, but it went through a lot of models, something you should really try to avoid, and it moved too suddenly (this is because you used waits instead of a timer/real system).
The camera in the center hall, where the two enemies are standing before eachother is sloppy: you should make the camera rise above the units or next to them, not through them...
At some point in the cinematic, the general and the warlord are in some sort of 'showdown', but aren't even facing eachother (they were facing downwards).
By now you probably think that this is a very negative review, but I actually rate it a 2/5 (Lacking), which is rather good in my opinion

If you at least add the proper credits, I can approve the map, but unfortunately: my personality cannot accept maps that don't give proper credits - call me old-fashioned, but I see no reason to change.
Status: Rejected (Until Updated)
Needs fix:
- Credits (add proper credits to all authors of all files you have imported).
- Terrain (only some minor edits, change the fog throughout the game).
- Misc issues (facing angles, camera through models).
- The dialogues! Please!
Of course, I could say that the triggering and camera would also need to be fixed, but let's face it: you need to completely redo the entire triggering in order to do this.
So I just suggest you fix the above and I'll approve the map.
Edit: I know that this is probably one of the 'better' cinematics (though I approved the others), but times are changing
