I wasn't having much luck getting any of these from Sarah as they didn't fit the profile for the editor being the colour ones were portraits that couldn't be altered to fit the template. She's limited to Landscape orientation or pics that can be fitted to landscape and she can't get it to accept black and white pics at all.
From the looks of these and considering where and when they were taken, I wouldn't be surprised if he had these done for new headshots for his portfolio, going for a more serious look to move beyond the final season of Sharpe.
