Awesome work on Vitani! I love her.
I really liked how her hair is on her. It makes her stand out as one of the main characters.
I might be wrong, but I think you colored her eyes purple.
Her eyes are actually blue.
Her eyes were colored purple while her fur is colored orange or dark-peach when she's a cub at the outlands in the film 'The Lion King 2: Simba's Pride'. [Link]
Seeing her eyes as blue is mentioned on this link, Vitani - Disney Wiki - Wikia, under appearance.
It was also shown on 2 other fan art on a different website [Link].
