usually, I don't comment much about technical aspects on photos post in Critique Corner, for that, you can get it else where.
I will pay more attention on the "content" of the photo, the subject, the message, the story etc..
You do have a story, but the photo you show here, does not carry, portray, or illustrate what you want to tell people, this is what I meant in my initial post.
You can have a technically perfect, nice composition, well processed photo, but photo without, or can't tell a message, it is still a snap shot.
You need to link all the key elements in your story into the photo, if you can't, than use a series of photos, to tell people about the relationship between all the elements in your photo........like....
You can take a long shot of your dad standing beside the pick up....
You can take a long shot of your mum walking towards your dad....
you can take a shot of your dad in foreground and when your mum walking towards him....
you can take a shot of your mum in foreground and when she is walking towards your dad....
