Portrait of a Brunette

Hello there! This is another big portrait i did, i really don't know who is she, i found the photo on google and i really liked it, i tried to find out who is she, but i did not succeed, if someone know it would be great. Hope you like it!
EDIT: Thanks to TheArtistofChaos on Reddit now i know that the model is Sophie Pumfrett!
