Very good image for a single shot or 5 Exposure Leo. Not sure which, you have both listed. All Clean except for burn area top left on rock formation. Thanks for posting.
If it is the 5 bracket picture I would say not do good A good HDR process has NO burn highlights just increase the number of shots and you are good
No.. Single raw.... And after brkting in Photoshop
Very natural looking. I like the water in particular.
