My third image
Think this image works really well as a square crop.
The lighting was trying to emulate the rembrandt style, capturing a triangle shape of light on the right cheek - whilst at the same time capturing contrasting light on the backdrop with a very light area on the right and a darker light on the left.
Was very pleased with the final print and composition.
It may be said that the logo on the shirt is a little distracting - yes it could have been removed in Photoshop, or could have been a tighter crop, but after some deliberation i settled for this composition and feel that the left eye has enough pulling power to draw your gaze directly to the image after you scan around the rest of the composition.
