Painting Epilogue

Yes, the painting seem to depict the popular story in chronological order, which was they met at a bridge, then fell in love, got married. Blanca got revealed. And Fa Hai captured Blanca. I am not sure what is the object falling from the sky. Perhaps this has to do with their son or the couple receive blessing from heaven at the end.

As to the chronology of Blanca's fate, usually Blanca would try to save Sean and get herself into deep trouble in doing so. Her punishment is eternal imprisonment under the Lei Feng tower. In some versions shes saved - most TV adaptations choose this, for obvious reasons.

Lake Creature

The lake creature is likely a toroise, as that would be most consistent with circulated versions of the story. Although it does not appear in pre-existing versions, it would make a very logical story that after 500 years, the Taoist general did reincarnate - as Sean did as well. And given he was brutally murdered by snakes, it make sense that he continue to hold hatred toward snake in his new life. Also, more accurately, his rank is not general, but the Imperial Maestro. Its a real rank given to the most senior scholar in the nation. Although in mythologies, the imperial mastro is often portrayed as a powerful wizard.

Sequel

The sequel was already announced by virtue of the movie's Chinese title. In Chinese, it translates to "White Snake: Love Begins". The actual character 緣 means luck or the source. When used in the context of a relationship between a man and a woman, it means they are destined to be together.
