Wow, excellent project ... and that's just from seeing your YouTube video samples! Version 2 should look great as well (hope you'll do more YT samples).

This may be a little late (and of course your sample are old), but I found a couple of things that could use fixing (?) OR at least to keep in mind for the new version.

The landspeeder shot on the way in Mos Eisley Spaceport is "despecialized" but the ink spot ILM made for a shadow screams "lame". As you've reworked that entire shot, how about fixing the shadow, too?

The top section is the DVD release of the laserdisc (thanks, George!). Ink spot -- no color, black crushed, and just doesn't look like a shadow.
Your "despecialized" is the center section. Looks great ... except for that ink spot. For this proof of concept, I used the ink spot shadow area to mask and darken the same area from the clean beginning of the shot, and overlayed that result onto this frame. This allows the now darkened ground texture to show through like an actual shadow. To take this fix only one step further, you might like to adjust the contrast on the speeder to better match the surrounding scenery (darks, lights, saturation).

Also, the beginning 8 frames of the "move along" shot was jarring and made me replay it to notice a number of areas that hopefully will be addressed:

frame 1 - garbage by helmet of center trooper; frame squashed
frame 2 - same frame 1 w/o garbage or squash
frames 3 & 4 - same frame
frames 5 & 6 - same frame
frame 7 - OK
frame 8 - frames 7 & 8 superimposed (looks blurred)

Thereafter, it looks and moves fine.
