Two suggestions:
1.) The ties don't appear to be making a graceful arc, rather they're making a sharp turn to the right. I'd recommend smoothing that out a little. (assuming that's not an artifact of the preview..)
2.) I'd have them go a little farther into the foreground. The A-Wing appears to be flying along-side the Rebel cruiser, making it look a lot bigger than it really is. (or maybe I'm just not getting the scale of it. I seem to recall the ships being smaller in comparison from RotJ.)
Looks great, tho.
