Damn I love finding video work like this. It's a passion of mine. I'll share my thoughts...

Pretty fantastic editing. I love the way it flowed with the music. The pacing matches the soundtrack perfectly. I have a subReddit dedicated to this kind of stuff so I posted it on there: https://www.reddit.com/r/SyncedtoMusic/comments/7hl8jt/darth_vaders_rage_anakin_skywalker_tribute/

That's a technical part I like about it, and overall (as for the experiential result of all that) I really appreciate the way I get immersed into Vader's character. I feel as though I am experiencing his memories and emotions myself.

On the downside, I think it became a bit repetitive – perhaps having it be a little bit more chronological instead of constantly showing clips from different times? There's definitely value in having it be all over the place – for moments of intensity – and those moments I think are actually what make this video stand out from most. But from a certain point on, I don't think it ever became recognizably chronological again. I think it should have a sort of gradual decrease in chronological chaos as time goes on, such that as you make your way back to the "present" (staring out the window) it becomes more and more grounded in the present again. Overall the chronological chaos could look kinda like a normal curve, instead of the way it simply increases as time goes on kinda like this curve.

I love doing this kind of stuff too. In any video like this there's a theme to get at. This video focuses on Vader's rage, clearly. I recently made a fan trailer for The Last Jedi. I found hands/grasping at lightsabers to be a very common theme in the recent movie trailers. I also focused a lot on making the music in sync with the visuals. Any feedback would be appreciated on that too if you're interested!

Thanks for sharing.

EDIT: I just watched again and it honestly does seem like you let the 'chronological chaos' calm down a bit at the end. Perhaps the scene of Vader walking by the Falcon just wasn't as memorable and so I didn't think to count it. Instead I think you could transition to the future a little bit, providing some resolution to his rage. Perhaps transition to Luke playing out the last of Vader's rage, in their final fight when Luke uses a lot of heavy attacks near the end of the scene. If it's more memorable then it feels more like you've resolved the rage, given catharsis to the viewer. The hard part with that, though, is how it would match the music at that point...
