Thanks, Bjørn, Elsa.
The image was of course shot from a tripod and leveled to help keep the lines straight in the brickwork, given the lens in use. A longer lens might have helped and I could have rented one, but timing and clutter were working against me. As for the color of the water as it was at the time, it's fairly true, as there were also leds on the opposite side of pool that were fluctuating between blue and green, the effect of which really shows up in the dark. Lastly, beyond keeping lines as straight as possible, I wasn't overly concerned with framing because I knew I would probably be using crops of any shots I took for prints that would be 8x10 inches in size.
Still, I never have calibrated the older monitor (EIZO CE240W) I'm using (I print very little), though Bjørn's comment has convinced me that maybe it's time to do so (and maybe even get a new monitor).
I've never considered myself a pro, but more a hobbyist, especially now as I've started to get back into photography again; and I do plan on slowly acquiring more of what I need, as my budget allows.
Following are jpgs of the raws as they came out of the camera, untouched, for context. Again, the blown highlights in the fires are my biggest concern here, and I would think stacking bracketed exposures might work best (if the weather behaves):
