Well, just watched it today. Overall, liked the beginning but the second half still suffered from Snyder's loud, obnoxious fight scenes. Still, you definitely did the best you could. As for the edited color scheme, it looked good with the exception of some scenes but even they weren't too bad.
Also, not the biggest fan of the whole title "Steel Of Man", sounds just wrong. Maybe something more simple like "Kal-El"?
Here are some other notes (some may already be fixed from previous feedback from other users):
For the opening logo, maybe make the Legendary logo normal so that it doesn't look like totally tinted red, and with the DC logo make the C part completly white so that it can stand out more.
Odd fade transition at 4:35. Maybe just have it be a smash cut?
Maybe also just remove the dramatic scream from Lois? I dunno, just always thought it was over-the-top and "OOOHHHH, WE SERIOUS" at least in terms of execution.
Around the 9:10 mark, maybe add an establishing shot of the sea so that Lois' line can end before you move onto the boat scene? As it is right now, seems too abrupt.
I'd say remove the Clark shot from 10:26 as it looks much too zoomed in. Go from the shot of the tower going down to the wide shot.
And remove the abs shot when he holds up the tower as much like the previous shot, it looks weird cropped and we don't see his face so having a front shot is kinda pointless.
14:56 mark, Clark's line isn't transitioning well to the flashback. Not sure though how you can fix it.
Remove "That's my name", Henry's delivery makes it less like "Is that my real name?" and more like "Yeah, that's my name".
I'd say keep the silver/grey filter for the entire Krypton flashback and cut it down a tad bit. As it is, it feels too long for a flashback like it's suppose to be. Just keep the bare essentals and what Jor-El brought up in the original cut.
For the end of the whole backstory flashback with Martha, have Clark's line "I know where I come from" be over the end of it and then fade back to present day. As it is now, there's dead space in the audio.
Probably not anything you can do, but man is the lens flair bbadddd when Superman surrenders for Lois
I feel like the transition from the interrigation room to out in the desert was a bit too abrupt
Maybe remove some of Lois' "Healp him!" when Clark is adjusting to the Kryptonian ship's atmosphere? Makes her seem a bit too (for lack of a better term) whimpy.
Remove Zod's flashback to being imprisoned since it doesn't really show anything else besides what he tells Clark. Also it would get rid of the ham that is Michael Shannon's delivery of "I WILL FIND HIM" and as much of the......phalic pods as possible
Again, not sure if you can do this but maybe remove the sea of skulls? It's just so stupid. Maybe a quick montage of what would happen with footage from world-ending films with voice-over?
Shorten the whole T-Pose (i mean "brilliant Christ allegory"), maybe just have him exit and then smash cut when he turns around?
Remove Zod yelling "WHERE IS THE CODEX". Again, Shannon hamming it up.
Remove the shot of the farm towers at 1:03:02 and just have it go straight from Clark going down on the ground
Remove the dramatic shot of Zod in front of the destroyed 7-Eleven and just have go from Zod standing up to walking toward Clark from behind
Remove Clark saying "Focus, you're getting everything", feels weird for him to basically say "Hey, you're getting all these powers that will cause more death and destruction!"
At 1:06:54, there's a harsh cut in the audio from the soldiers yelling to the next scene
1:08:37, odd harsh audio cut between the scenes
Possible to remove the lens flare after the guy says "No" around 1:14:21?
Harsh music cut at 1:17:58 and 1:18:10
Coughing SFX at 1:18:21 sticks out way too much, understand the intention but it does not blend well at all.
1:19:41, hard audio cut.
1:19:55, coughing SFX again. Honestly it comes off as comedic
Remove the cliche "twice the man you are line" from Jor-El's ghost to Zod
1:21:58, hard audio cut
1:22:14, ibid
Remove the guy saying "Northcom....", line is cut way too early
1:24:11, audio cut but not as harsh as other ones
Remove the whole "Krypton had it's chance!" line. Enough with your edginess, Snyder..
Remove the dramatic stare-off with Faora and the army guy
Also remove Faora's head tilt from seeing the plane about to crash into the Krypton ship
Remove Zod's whole "I WILL ERADICATE HUMANS" and "ON A FAHRM" spiels, have him be basically silent with rage throughout the finale. More menacing that way and might imply that, since he was only born to protect Krypton, loosing his race made him lost whatever humanity he may have had (least just a thought).
As for the neck snap, maybe have Zod already start blasting his eye beams close to the family and make the neck snap a knee-jerk reaction from Clark? With the flashbacks to the tornado, you could have it where he freaked from his PTSd of the event being triggered
Remove the flashback to Clark wearing a Red Cape, doesn't really make sense for Clark to dress up as Superman when he doesn't even really exists yet (poorly executed foreshadowing on Snyder's part). Though maybe repurpose it to another kid being inspired by Superman?
Have the whole "Perils of Perry White" segment be a separate short instead of a post-credit scene. Like Marvel's One-Shot.
Also, speaking of repurposing the aforementioned Red Cape scene, maybe use the beginning phone scene from the theatrical Justice League and combine those two with a montage in the end of Superman doing heroic acts (possibly from Superman and Lois) to show how he's inspiring people? As well as Clark showing up at the Daily Planet.
(Know that JL scene has the controversial "Deepfake lip", but it honestly didn't bother me and you could always use one of the "fixed" versions on YouTube)
