|Greetings from Critique Club:
First entry into a challenge and a 5.9 score...not a bad start.
You did not post your processing steps, so I will have to try to guess what you have done. The shutter speed and ISO suggest that you have either contrasted the image or saturated it to get the darkness and colour, and it worked. Perhaps there is a hint of USM/sharpening also, but it has not been overdone. Also, there is a touch of grain/noise showing which might affect how this prints up at full size.
A good composition using 50/50 technique and this work nicely with the reflective quality of the water. A well balanced image, clean and striking.
There are a few landscape photogs here who will need to watch their laurels! A good, clean and colourful scene. The 50/50 format allows the water to reflect the sky beautifully. You were approaching the limit of your camera here with the noise/grain beginning to show, but it doesn't spoil what is a good image. It is a different angle on the delicate challenge and I agree that Nature is more delicate than many believe. I look forward to seeing more in the future, this is good start and will get better. I hope this is helpful and constructive.
