To answer your question "I'm not sure why a shirtless man is posing in front of flowers?": because I think it's beautiful.
The nice thing about posting on TPF is the variety of opinions that come when you ask for C&C. However I think it's important to remember that once you get past technical aspects, it becomes highly subjective. What we like/don't like is tempered by our own personal tastes, experiences, expectations, and may be very different from someone else. Doesn't make them wrong or right, just different. It's up to the person doing the posting to determine the validity of the subjective comments, how it relates to their own opinion, and if adjustments in thinking need to occur.
That said I think the poster was trying to say something similar to what I pointed out earlier with his comment
"I find the bright white flowers distracting and think more attention would have been drawn to the subject if you found an area of greenery with some light filtering through creating patches of color" In the first shot the close crop and shallow DOF caused the flowers to blur into the back ground and not compete with the subject, but on the second they are a distraction, especially on the left side.
