That's excellently drawn... a fitting tribute to ROTJ!
I have a great fondness for the original trilogy Star Wars movies. What impresses me most is the level of artistry and craftsmanship that went into the special visual effects of that pre-digital era... the miniatures (models), the matte paintings, sculpting of the creatures, animation FX, etc.
If you've got an hour to spare, you might like this 1984 documentary featuring the work done by Industrial Light & Magic on Star Wars, Indiana Jones and other movies of that time...

The segment on matte paintings is especially interesting, IMO. Click here if you'd like to skip straight to that point in the video.
