Adywan, having looked at the 'asteroid slug' sequence now, I think that my recent speculation that the Millennium Falcon's front 'bright, white' lights (if supposedly on again at this point) would maybe shine on some tooth or other as it escaped....was probably wrong. The 'beams' from them doesn't seem to be particularly strong in the scene where they initially come on, and anyway, the Falcon is going in-between the gap between the teeth, rather than directly towards any of the teeth! So scratch that thought I'd say.
However, what I did notice now, was that during that shot of the Falcon where it's front 'bright, white' lights come on....the actual 'opening' behind it in the distance is WHITE, and doesn't seem to match the shape of the 'opening' it entered either....
Perhaps this could be made to either look like a hint of an 'open mouth with teeth' instead (if you consider it to be near the actual opening at this point in time that is, as it could be further down the 'cave' at the moment, before the Falcon enters it)....OR perhaps it could be made to look more like the shape of the 'opening' hole in the first place.
Either way, it would be good to have the blackness of the 'starfield' showing, perhaps with a small 'asteroid' drifting past 'overhead'.
Finally, should we see some tumbling asteroids in the distance, beyond the 'teeth' of the slug also?
