Sounds pretty good in terms of matching with JEJ (though there is a noticeable shift in volume at :54). The scream itself is not great (sounds a little like gagging - though I suppose he would actually make some weird noises with his new physical condition) but it is better than “Noooooooo” so maybe it is worth the change.

Also, have you done something with the color there? Seems like there’s some added contrast and maybe a bit of blueish tint? Anyway it looks fantastic, especially the shots of Obi-wan.
