Nice little video you got there ady :)
I see you fixed the lightsaber continuity error when it was dropped too :D (i think its reversed footage isnt it?) (see pic)

Good to see the additional vader's saber behind the smokes and an onscreen ignition of luke's saber :D (see pic)

When Luke flips behind vader luke's saber appears too short even in the previous frames it appears big. (see pic)

I like you kept color continuity in all the carbon sequence.( see red hue in the blue color)

There is a misrotoed saber blade originaly and yo your version.(see pic)

I really liked that you masked out luke from the overblown clash flash ;) (see pic)

Some akward movement from the original roto is still there like the animators couldnt rotospope the saber properly back them because of the smoke. It might need to smooth it?
In some parts the blue of luke's saber is over blown on vader's cape. Can you try to reduce them adding a darkening mask around vader's silhouette?
