Great wrap up for a great series.
And that's a wrap! I'm amazed you follwed through and worked on this series of yours so thorougly, it turned out great. Your visuals turned out great in the end. It was good to see massive baddies getting rocked, all those explosions didn't hurt a bit. The audio was flawless, all sounds and music that would have been required was met and surpassed. I really liked the sense of style in this movie. The battle scenes were great and it had a nice story that had a personal touch to it.
Oh, since you asked for suggestions, the only thing I could really recomend for future projects is a really dramatic finish. Don't get me wrong, the end here was nice and heartfealt. I just mean something like a climactic battle where there's a good deal of environmental and character damage. I only mention it because of that really cool X4 teaser you put in at the beginning (badass) sounds like it's setting a serious tone. All in all, everything was great, all the way to the expanded dimensions of the movie that gave it the cinima effect. Great job on the series, you've done great, my friend.
