The Daily Mail said her work caught the eye of prosthetics designer Neill Gorton, who has asked her to attend The Prosthetics Event, a conference in Birmingham that takes place next month.
The newspaper quoted her as saying, "I didn't think anything would come of it but the reaction to my work has been incredible. I don't really have an idea in mind when I start to paint. I just start and see what happens."
"I started painting my kids' faces for Halloween, then I asked Craig [her husband] if I could paint him as well. But I knew I couldn't paint on them all the time so I started painting my own face."
"I started to think of ways I could make my work different. I wanted to stand out and try new things. Luckily it has paid off."
Shelley said on her Facebook page that she now offers her talents at events such as birthday parties and weddings.
According to the Mail, Shelley hopes to move into prosthetics and eventually work in TV and film.
