Since I gave a long post of feedback for PotS's characters, thought I come back to Guy and M.Bison to see if any issues shares with yours and noticed a few things that were missed previously:
-The hitsparks on his special intro with Cody/Haggar are layered behind the barrels and use guard sounds (When Cody or Haggar does theirs, I realized they are layered in front and use strong punch hit sounds).
-The sliding dust on his run stop animation is the not same position as Hayagake's one.
-Seoi Nage is still missing the strong kick swing sound when the opponent is thrown.
-Hayagake is missing the running dust effect when he starts running.
-His crouching HK is missing the running dust effect when he skids (Since I saw it on the M.Bison edit).
-The hitspark and guard spark of standing MK is still misaligned when it hits the opponent slightly farther away.
-There is no jump sound effect when he leaps from Head Press when it connects.
-Level 1 Knee Press Nightmare doesn't have running dust on the last hit like the crouching HK (Although PotS didn't have that dust, though you could for the sake of consistency since either you or Froz have it).
-There is no landing effect when he touches the ground after the end of Nightmare Booster.
I will still do detail and aesthetic feedback for the rest.
