This gives me bleach vibes

Will there ever be more gunmetal black?

Your Animation skills are good. I think you did a great job on this one. Graphical it looks convincing and if you look away from all the other 3D-Anime I think it ranks up well. My points for improvement: More fluent animation and better choreography for the action scenes. Sometimes it looks like I'm looking at 10FPS and sometimes the characters barely make contact or there is a "big" pause before contact.
in short, I think you're coming along just fine. Maybe giving your work a second look or a second opinion by someone else will improve the final product even more.

Neat!
I second some of the things pointed out from others. But lets focus on a ew details.
The scene where your protagonist 1 jumped down the building and used her ropegun a few times. Was hard to read, brought no insight to the watcher. Maybe some detailed shots including a shot from the gun or the point where the hook caught a hold, combined with a more clear movment maybe a swing directly towards the camera, a cut with a clear movment with head, arm and the rest of the body indicating a direction change, followed by a landing. If you could alter the ropegun sound slightly it would help to avoid the soundbitey feeling I had.

I applaud your fighting scene, well done in that matter. For my taste it recycled the same movement to much. That is not really a problem, but seeing this from the very same ancle in the same shot makes it very clear for the vewer, at least for me.

I enjoy the concept of randomly tapping into a whole storyline not known to the viewer XD

I hope you will blast out amazing work in the future!

this needs a REBOOT
