Author's note:
Gotta keep the expectations modest here, it seems as with any unique concepts with intricate details and little data; this LoRA is pretty rough. It's furthermore limited by PixAI 100 picture limit.
Still you should be able to get a functional picture on a consistent basis of the ship.
I recommend using models focused on realism like JayNL
Historic detail:
After the Sengoku Jidai period of Japan, Hidiyoshi turned his attention across the sea with the purpose to invade Ming China, to that end Japan invaded Korea first to reach the mainland of China.
During the Japanese invasion of Korea (1592–1598), the Koreans under the Joseon dynasty quickly losed many provinces, with the Japanese capturing crucial areas including Pyongyang and Seoul.
Yet as the Koreans kept losing on land, the navy was a different story. Under the brilliant leadership of admiral Yi sun-sin , the Korean navy scored crucial victories against the Japanese. Among his brilliance was designing the geobukseon (turtle ship in English), having enclosed covers all over the ship and spiked deck to dissuade Japanese boarding tactics. The turtle ships would prove crucial to many of Yi sun-sin's victories untill he was demoted due to the political enemies he made (before being promoted against after the disasterous battle of Battle of Chilcheollyang).
While the turtle ships were likely not present at the final days of the war, it remains a potent symbol within Korea.
