'With cowboys, I am drawn to the great state of Texas - where the most authentic, uncompromising, working cowboys in the world live their lives. The flat and arid, big sky topography of West Texas offers a distinctive canvas that not just locates an image, it also lends a stage on which to take a dynamic portrait. Texan cowboys are the real deal and the vastness of west Texas is their workplace. On set on the Rio Grande, which divides America from Mexico, I met a working cowboy called Ryan Marshall and knew I had to take his picture. The photograph wins because of its vitality and power, but also because of Ryan’s anonymity. I am an eyes person, but on this occasion, we don’t need them. This is west Texas and all the ‘True Grit’ that goes with it.'
