I would keep this shot clean of any added SDs, being that the IMperial Fleet would be "behind" the camera view.

This is where I would add the rest of the Imperial Fleet in the background, about half the size or smaller than the Avenger (since the Avenger was rushing to make the first kill).

I would add the background fleet in the later part of the camera pan here, to show them closing in.

You could maybe add some tracks here to show that Luke has at least walked from over the ridge (from the center to the lower left). I see now that there are tracks directly behind him (so this is a very minor alteration suggestion), just a suggestion so we can better see the tracks.

Could improve the background sky area.

I would replace the Executor with two or three disabled SDs off to the right background, to imply that the path the rebels took (and the previous location of the Imperial Fleet) was way off to the right.

I would keep this shot clean, as of by now Luke would be far away from the main rebel escape point and the ion battle. You could possibly show the stars start to speed up as Luke increases speed to prep for the hyperspace jump.
