When I have watched Elena Of Avalor I seem to think the character Luna the Jaquin has Yvette Nicole Brown's personality and humor and when I see Luna I think that the main reason why Yvette Nicole Brown was chosen to provide the voice of Luna for Elena Of Avalor. I also discovered another reason why Yvette Nicole Brown was chosen as Luna's voice actress that I find surprising and shocking to me. If you look at Luna the Jaquin really closely you'll notice that she is orange and when I saw Yvette Nicole Brown's Big Lots commercial the logo of Big Lots is also orange as well and so it tells me that Disney based Luna on Yvette Nicole Brown and got Luna's orange color from the Big Lots logo too

Hi, Bestie! I have heard that Disney tries to put some of the voice actors character in the drawings, so you may be right.
