Oedipus and the Sphynx Picture

So, my school decided to throw a sort of a charity project for the families who can't afford the school materials that students are in need of.

The students could choose to do a project based on a drawing, painting, photograph or whatever media we wanted, based on a book or story, and it would be displayed and sold in our school hall. The money goes to a school fund for families of students in need of economical help.

My project is a watercolor illustration of Oedipus's myth, it will be sold for 20€, and I'm glad I could find some spare time to collaborate with this amazing project.
