I think "A walk in the park" would be more appropriate than "Nature walk" for a title. This is clearly a human-made environment, even with a paved road/walkway on the left.
The foreground appears a bit empty to me. The walking person is not prominent enough to draw much attention and be the main topic of the picture; but it's again not far enough away that it can be taken as part of the scenery. To me, it is not evident what you want to show.
I kinda second the opinion from Wiz that the B&W might not work here. BUT its o nly an opinion. Perhaps if it was like a very nice saturated tone of green it might work well with the title. NIce try thou.
