Just some thoughts...
I liked that he removed the yellow/green color from the panel room when piet informs vader.
Palpatine's clarity and the quality of the hologram is top notch.
I see he replaced again the top section of the background when we see palpatine's face from front.
There is too much interference and shaking in the holo.
Quality noise in between frames that shows the noise/tremble effect.
Behind palpatine the background looks too static. There was a little light that were blinking in the dark rentagle in the wall.
The audio is temp but still i judge what i saw. The lip sync was poor.
Vader's close up after a while was reversed footage.
I like but i dont if its correct that the lines in the side view to be angled and even the holo animation lines follow that. i like the aggresive look still it might be an artistic choice.
The glow in the emperor's side view was too clean. was begging for some grain
The changes between the clean and the distorted signal are way too fast. if they could be slightly slowed down it would be ideal.
