Kerascoët is the pen name of Marie Pommepuy and Sébastien Cosset. The artists work collaboratively in Paris on illustration and book projects.
Their website Kerascoet.fr contains ink and watercolor drawings of characters and fantasy worlds and many in-progress photographs of comic work being inked and colored. A bibliography page lists the substantial collection of comics and books that they have worked on.
Kerascoët also has a Facebook page here.
