3PO going to Jabbas palice could do with a futher re-do. Maybe put the droids on a narrow path leading upto the palice . Add a few hundred foot drop on the left hand side (even i can do that) and it makes the entrance more precarious (as i suffer from vertigo)

Again, what for? It has absolutely no bearing on the plot whether their journey to the palace was easy or not. The only reason we see them approaching at all is to establish the Palace and inform the audience what the situation is. Adding something like you suggest is distracting from the function of the scene.
