Torii? Maybe this scene as well https://www.sakugabooru.com/post/show/47706 ?

Definitely a possibility. the water resembles his current spark effects style a lot. Looks way different to his old water effects work but then again that work is over 8 years old at this point and he's evolved a lot since then. It also reminds me of Masahiro Sato's similar Yutapon inspired water effects.

That other scene i'm not sure about.
