She has a feather in her hair, so wouldn't that make her Lumine and not Lisa?
The original may be deleted, but you can still go back and check the artist's other works. They have Lumine with two feathers as seen here: post #4287271 post #4476121
On the other hand, they have Lisa with not only 1 big feather but also as a common ship with Venti as seen here: post #5043727 post #5653277
