Face with dots

I made this for my Illustration Techniques I class. Made with only dots (i don't know the name in english; in spanish is "puntillismo").

Yes, I took the reference from a deviant artist here, but I've lost his/her address. If someone knows whose this photo is, please tell me to link it. And if the author of the photo doesn't like my work and he/she wants me to erase it, he/she has all the right to ask me to do it.
