“Anakin look updated in flashbacks” (discord faq)
“Anakin/Obi-Wan training sequence is sprinkled through the film where it makes sense instead of all at once” (reddit comment)

Above is all Pixel has mentioned about the flashbacks. Hopefully he adds some much needed changes in these scenes. I did a little mock up of what looks a little better in my opinion. Changes include…

Major color correction on entire scene, and especially on both faces. It’s way to pink and de-saturated
Obi-Wans robes are pink-ish, even after color correction and need to be a little tan
Obi-Wans hair needs more orange in it
I think Obi-Wan needs to be de-aged as well
Needs Coruscant traffic in background
