As @Kevin-Longueil says, color and lighting schemes belong to everyone - part of the wonders of the world 😉
Doing the same animal with the same light and color treatment will obviously seem derivative to people who know both you and your inspiration. But Annie Stegg is also derivative of many others before her (I can see hints of several sources, including Renaissance art). As the saying go, plagiarism is stealing from one, originality is stealing from many. There is another quote which I like a lot "the growing artist borrows, the established artists steals".
So, by all means you can use her color scheme, understand it and make it yours!
