Well, I finally got to see your edit after so many failed attempts on downloading it, and here are my thoughts:
(Sorry about the very long text)
I like the idea of trying to tell a parallel story between Anakin and Luke, and it might work, but with some changes like the ones mentioned before me.
The placement on flashbacks is not bad at all, BUT, in my personal opinion I dont like it some of them(for example, I would preffer to match Luke watching the suns paired to Anakin watching his mother as he leaves, but idk if there would be enough time to tell TPM story that way), but my ideas wouldnt exactly work(i think), and sometimes the flashbacks feel too long that they could detract attention from ANH. The “32 years earlier…” works as how it is, at least for me, another crawl so early on the film again or even a second crawl at all, i dont think that would be a good idea.
Maybe the moments of TPM could be a bit misleading, specially Maul, it could detract a bit from Vader as for main villain, to be honest, I was expecting to see a quick cute to Anakin blowing The Federation space station before we get to the Death Star attack, it would had be a cool mirroring, but, now that I think of it, maybe it wouldnt make a lot of sense due to what is given from TPM via flashbacks.
I dont feel the cuts to be abrupt, at least not visually, the fading to black was good, and they are the correct speed for me. And the subtitles where fine, I didnt saw any errors.
It was a well condensed version of TPM, and I liked how the death of QuiGon could be paired to the one of Ben Kenobi, both apprentices lost their masters. The characters from TPM, well, its all fault of the source material really and the idea of making flashbacks from the movie, so, altho some feel a bit ‘‘meh’’ (Sidious and Binks for me), they are okay. And I didnt liked the voice of JarJar at all, really, it felt wierd to hear it, unnatural, is it backwards? And C-3PO out of TPM, good idea.
The way TPM was modified to look more old, with the film grain and contrast, i loved it, it looked really good, I would had liked to watch more TPM with that filter. The quality wasnt a distractor for me, but maybe it could be enhaced (i really dont know about that), and in my opinion you should had used either Revisited or Despecialized editions as base for ANH.
Fun fact, ANH audio has always bugged me, i dont know if I have such bad luck to always find a version where the quality of audio randomly jumps and varies a lot (i think the better example i could give would be on Luke’s room when he is cleaning the droids). I do think the ones that bugged me the most where because of that and not your editing, altho a quick cut between voices in TPM where the Queen and QuiGon decide to where to go each other when they are on the hangar and Maul appears, and also on the Deaht Star battle, I heared a quick short jump between music and effects, altho i cant remember where exactly. Replaced dialogue…I can only recall the one on the Padme throne room run/hangar, and the jumbling of the score, I noticed it too, not thaaaaat distracting, but noticeable anyways. The music to podrace, was good, yay.
The Mos Eisly Droids, you reffer to that scene where there was a big Ronto blocking the view before? Yeah, it looked noticeable, and also too yellow in comparisson to the other shots of Tatooine. I dont exactly know what you took out of SE appart from that, I could even say that you keeped all of them haha. The new Alderaan explosion looked really cool but, not very adequate for ANH, it looked ‘‘to modern’’ for the old footage that ANH brings. The flashbacks that Ben Kenobi had while talking about Anakin look convicing enough for me, but it looked a bit wierd that two of them where from ROTS and one from AOTC, but the AOTC one is the best to depict ‘‘and he was a good friend’’ line so that doesnt really matter, and the one where he is supposed to see Anakin burning, was good. The Death Star explosion, well, I like the idea of the 8 ligths being on and then exploding, but, its obvious to me that the explosion itself its from TFA, I can even see the rectangular dish of the Falcon and the quality its too high in contrast of ANH.
Overall, I liked the idea and Im totally positive on watching the next chapter on this project of yours:)
