The water still looks over sharpened in those two for my liking, even without zooming in. The sharpening looks similar to what I see sometimes when I push the sharpening too far in Topaz's Denoise or Sharpen.
If you like the look of the water that's fine. How much sharpening one applies is subjective to a large extent.
How much sharpening did you apply before downsizing?
Great photo and the water looks fine to me although I am not one of those purists who seem obsessed with zooming in to pixel level just to see how sharp it is :)
