Not to be a jerk here... But... I can't help but think that Rosalina doesn't... Well... I don't know, I still feel like the vertex gets the job done better as a Brawl version of her... From the looks of it, this one has no mouth that moves. It's painted on...
If a version 2 comes out in the future, it should be a hybrid of the Brawl Peach model, and this Rosalina model... You know, mix the two models into one Brawl like Rosalina model. This should be possible.
funny you should mention that...
focus on the mouth, not the extra stuff i didn't fix. i just took a quick pic but didn't feel like fixing everything up at the moment. but yes, i fully riged the mouth to open, just like Peach's. when i make a rig, i make it as perfect as possible.
