Wouldn't be surprised if I'm in the minority about being bothered by this (I usually am with my ESB Falcon engine issues), but in this particular SE shot of the Falcon flying through Cloud City, I strongly feel that the engine glow is extended too far out.

In just about every other shot of the Falcon from a side view in the OT, the glow never extends this far out at all (including the launch from Hoth when Luke is walking in the foreground.)

The only time the glow should extend like this is in scenes where the Falcon is blasting off (like the Docking Bay 94 sequence in ANH or when the Falcon turns around to face the Star Destroyer in ESB), but in this Cloud City shot, it is very clear that the Falcon is just coasting along at a cruising speed, so the glow seems to be overdone in my opinion. It looks worse to me in motion, but I didn't feel it necessary to post a video with no mock-ups done to it.

Just a thought.
