Originally that version of Dokibird was just an OC that she used to represent her as an artist.

The new model is a combination of all of her old avatars. That scarf/ascot the she wears? That's from back when she had a blue bird avatar. The hair and eyes are taken from the klaeia model, face/pose from Selen, etc.

It was just a different time and the new one was meant to represent her going forwards as a summation of all her experiences and accomplishments, as well as the kind of content she plans to put out.
She can pull out all the older ones at any time (and has even more plans to refurbish them), because again, they're all still her.
