For some of my environmental portraits some were more successful than others and I can show this with the way that they fit into the rule of thirds.

Below shows one of my more successful images for environmental portraits you can see that the figure is towards the left-centre segments this fits well with the rule of thirds.

Below again shows one of my less successful images, the subject is directly in the centre of the photograph which isn’t as successful in the terms of the rule of thirds.  The below image can be still seen as successful as an environmental portrait however it is let down in its strength with the rule of thirds.
