Exercise: real & implied triangle (implied)

This is my cat Travis, his eyes and nose create this implied triangle with a dowward apex. I took this image outdoors, cropped it in photoshop elements, but it wasn't quite symetrical, so I used Lightroom to turn the image ever so slightly to ensure it was as level as possible.
