Sorry I'm a bit late to the party, but I honestly think the image in your very first post would be the best solution. It's obviously from a promotional poster, which clearly shows his face and he's better posed to the camera. The other images in your most recent post are from the show's still photographer... also nice, but not quite the "hero" images that would end up on a poster.
Try to make it match your
Season 1 cover... add some rain and some lighting effects (among your other usual tweaks) and I think you can make that first image work.
