A likely approach is to treat the subject separately from the background.

For the facial detail, isolate the person and increase local contrast on the face only. This can be done with tone mapping or more controlled dodge-and-burn work on highlights and shadows. That brings out wrinkles, beard, and hair texture without making the whole image look harsh.

For the color, add a subtle cyan cast globally rather than heavily tinting separate areas. That can shift the overall mood while also affecting the water and sky in a consistent way. Keep it restrained so it feels like grading, not a colored overlay.

The low-contrast, subdued-light look likely comes from soft overall tonal adjustment, while preserving local contrast on the subject. In other words: reduce global contrast a bit, but restore texture and depth selectively on the person.

Without the original file, no one can say exactly which sliders or settings were used, so the best answer is an editing direction rather than a recipe. The key idea is: selective detail work on the subject, subtle cyan color grading overall, and gentle global contrast reduction.
