The one I’d for sure cut is @ 0:37. For what it is, it’s a good effect, but it lacks the complexity of all your other effects, and the one right after it has the same stylized feel while being more interesting and complex. I was waiting for something to happen after the lines traced on the ground, but then it just moved on to the next, so it’s just kind of a visual speedbump.
I think you can cut out the first 5 seconds of the space scene, and fade in right when the meteors start shooting by.
I think the first weapon swipe + dissolve effects are cool, but they could use just a tad bit more polish. The only negative things that stood out were your trails not matching up with your animation and meshes. Other than that, I think the colors and materials are really good.
One last thing I’d suggest is just put your same name and contact info again at the end. That just helps connect your work with you name, especially if someone is going through a dozen reels that day. Your reel is less than a minute and you already fade and hold on black for a few seconds. You can also have your name and contact info sit for another second on your opening before fading in to your work.
