The character William (AKA Bill) Rogers, who is seen from episode 3 of the Anime OVA series MSH (again, avoiding using the full title of the series to avoid LORA issues with the publishing)
Key words: tall male, blonde, blue eyes, upper body, pool scene, handsome, highly detailed, highest quality, vintage anime.
Highly suggest close up shots, as anything further away significantly degrades the quality since there were not many scenes to train this LORA from the Anime itself.
