I don't suppose I'll get away with asking you to stop mentioning that, will I?

Your conversions are consistently as good as anybody's conversions, so it really doesn't matter that you're new at it.
I don't see anything sinister in the monochrome version of the inlet. Instead, I see the lines and textures brought out more in it. It turns out that the scene impresses me as I expected, that both versions are of equal value for different reasons.
The photo of the silos displayed in monochrome is also as I expected, a nice improvement over the color version. For me, the color of the wood silo is a problem in the color version. It sticks out from the line of other silos and its central location within the line makes both that line and the overall scene a bit static. The monochrome version allows its tones to blend in with the other silos.
If you had devised a composition of the color silos so the wooden one was not nearly dead center within the scene, doing so for me would make the color and texture of its wood not only stand out more but also contribute to a more dynamic composition.
