Using the Battlefront tunnel element:
Nice! That definitely works, good job. The video quality of the vortex looks a bit blocky from the YouTube compression, perhaps an alternate source can be found (4K maybe?) or some radial blur could be added to smooth it out. I also feel like it could use some stabilization (it feels a bit shaky) and some grain to match the film footage. Also, there’s an issue at the end of the clip, the vortex jumps to a new position for a few frames.
