Create a photorealistic image featuring a Krogan from Mass Effect, fully armored in traditional Krogan armor with a rugged, battle-worn look. The Krogan has glowing red eyes and stands in a lush, green pasture next to a human shepherd who is herding a flock of sheep. The Krogan should be towering and imposing, yet slightly out of place in this peaceful rural setting. Include a text bubble coming from the Krogan that says 'Shepherd,' as a playful nod to the Mass Effect character Shepard. Ensure the scene is rendered in high detail, with a realistic portrayal of both the Krogan and the pastoral landscape."
