Another example of the colour, mono shape change. First the colour image.
The colour image has only two strong colour elements. The mans warm skin tone, matching in with the woods and rusty metal and the contrasting blue in the tub and his overalls. In this case I really like the play of the two complimenting colour groups.
The mono image arguably has more texture/character, but the impact is lessened in direct comparison to the colour version. I also think the man blends into the background too much, but a bit more processing could help that.
Again, you may disagree. I find when I am in a strongly colour or black and white only mood, I tend to be intolerant of the other.
