And that brings me to something else I wanted to bring up about this overall scene...
...is it just me?...or does it kinda seem like Luke has not fallen all the way down to the bottom of the chasm in the overall scene...but instead looks like he's being *sucked in* mid-fall towards the side of the chasm...before he actually reaches the bottom?!
Here's some screenshots to give a rough idea of what I mean, although it's better to study the moving footage itself -
Luke is falling directly downwards in the middle of the chasm at this point...
Shot 1 -
...and continues to do so in the shot below, passing several surrounding groups of red 'vents' at this point...
Shot 2 -
...and then we cut to this next shot below, where it initially seems as if he's still falling down the middle of the chasm...
Shot 3 -
...and looks like he's continuing to fall down the middle, down past even more groups of similar red 'vents' that are surrounding the side of the chasm...
...but then around this point in the shot, the footage kinda makes it look as if Luke then goes from falling down the middle of the chasm...to being 'pulled backwards' towards a group of surrounding 'vents' located further down at the side of the chasm!...
...just sayin', lol.
...however, although shot 3 above is a bit of a deceiving 'optical illusion'...I guess if I want to make it work better for myself in future, then I'll just have to start 'imagining' that we are now indeed looking directly down at the bottom of the chasm at this point...and will have to think of this particular matte background as being a rounded, concave shape...similar to looking at the inside curvature of the bottom of a 'test tube'...
