Just a few suggestions for PT:R.
EP1
When the Queens starship is running the blockade, show the reactions of some handmaidens and troops on the ship, if possible even the Queen herself. I have always found it strange that she is barely featured in this sequence.
Show Anakin losing a race to Sebulba who cheats.
After R2 repairs the shield generator, he drops back down the shoot, we then show the Queens starship making the jump to hyperspace. Whilst in hyper space, Captain Obvious notices the hyperdrive is leaking the ships sub light engine cuts out resulting in them ending up in the Tatooine system.
Maybe have a few abandoned starships in orbit. I never got the feeling of danger on Tatooine that I did in the OT.
If the Pod Race is going to be left in, I would suggest either replacing the pods with T-16’s or Landspeeders (though I highly doubt that this is feasible), in which case I thinking removing the colour schemes from the pods and making them rusting and beat up would suffice. Obviously I would also remove the commentators.
Show the Sith probe droid seeing the Queens cruiser. It does in the screenplay.
