nice collage work vanyoda. i like the spacebattle scene, few if any have even attempted it.
tips:
-mute R2's colors to match the color saturation of the rest of the picture
-drop some of the brightness out of anakin's face. very nice work in integrating him into the cockpit BTW.
-that federation ship on the lower left really bugs me...i dont know if its the edges, the lighting, the placement, or a combination of factors, but it appears to be miniaturised and hovering directly over the parasite-droid
-maybe lose a couple of parasite droids as well...it seems a bit overkill.

a quick ink sketch i just made, cause i'm bored at work.
this is the way i visualize vader after the duel.
(as im sure some will disagree)
