Morrigan is a celtic Goddess of battle, strife and fertility. She comes in many forms and is sometimes referred to as The Morrigu and can appear in three aspects; Badb ("Crow"), Macha (also connotes "Crow") and Nemain ("Frenzy"). She is often represented by a Crow and in this form, is said to have flown over battles as she selected which warriors were to live or die. She is also known to appear as a washer woman, washing the clothes of men about to die. Despite her disturbing role, she maintains the great balance between life and death, mirroring the role of all Mother Deities.
I just (like 10 minutes ago) finished reading the book Ravens of Avalon that dealt with the Goddess Morrigan and Queen Boudica. so your art certainly represents Her, i think.
