Lisa, this is a fine image. I like it as presented. I’d classify it as an artistic approach to a natural scene. Leaning towards a painterly look & feel for me…
I’ve never done any HDR so I cannot say overdone in that arena per se…
The processing looks fine to me, Lisa. It’s certainly visible, but it gives it the kind of look that a lot of painters would use and isn’t at all offensive. I like the processing very much. I think you might have been able to get a stronger composition if you’d rotated your camera just a bit to the left. The lone pillar unconnected to the rest of the pier with that relatively large gap between it and the rest looks a bit strange to my eye. The light in this image is wonderful and for my taste your shutter speed was just perfect.
