Hello, after asking, I can definitely answer you:

The name of the image is Miss Pepper, which is the original head portrait of Nanjing Beiling, a painter from Shijiazhuang.

You can get some information by typing Miss Pepper and Mr Pepper in Baidu. If you input from Baidu pictures, you can also see many pictures. One of them is yours.

Not a character in an anime, comic book or movie? And there is not much information on the internet.

I hope it helps you. Good luck! ~
