Ohhh, I think this is the first couple where the expressions differ between the characters. I really like the fact that you put enough personality traits even when they're dancing, so people who don't know the anime can also get the know these people.
Great movement flow, and your deft choice of colours are great once again :).
Yeah, this couple they have widely different personalities; Ladd is bombastic and absolutely buckwild while Lua barely shows any emotion.
