More impressive with realistic models.
Another prompts: alien face tattoos, alien tattoos.
Adjust the pose.
Strength: 0.7 -> 1
Illustrious:
Better than the other.
More impressive with 1 but but the image may need to be reworked.
(realistic screencap:1.9) for more realism, by removing it the character becomes less static.
Be careful, small aliens may appear in the image, use (Solo:1.9) or higher ! ^^
