Whoa....really nice addition Ady. Great collaborative effort. It's a fine example of a small change that just adds a nice subtle touch. Thanks as always for sharing.
Speaking of little changes....a while back I suggested maybe when Vader uses the force & starts throwing things at Luke during their fight perhaps the objects could spark a bit as though they are being torn from their place...(something like when Vader goes nuts at the end of ROTS) might you be doing something like that?
