Born in Spain, Amaya formally began studying art at the age of 16 in the School of Arts of Pamplona. After graduating in 1994 she began studying under the Spanish painter Mikel Esparza and was encouraged to move to New York City in 1999 to broaden her studies in figure painting and drawing. Over the next ten years in New York Amaya studied under the tutelage of various prominent painters at The Art Students League, The National Academy of Design and The Grand Central Academy. 

Throughout her education she was awarded several scholarships including the Evelyn Chard Kelley Memorial Scholarship for women painters by Pen and Brush, the Three Year Certificate Travel Scholarship and Newington-Cropsey Award from the National Academy to study the Italian masters in Italy, as well as being selected as a Hudson River Fellow by The Grand Central Academy for two consecutive years. 

In the course of her time in New York she worked as a mural painter for the companies Evergreen and Khuzami Studio, participating in different projects including the mural decorations for the Hotel Atlantis in Dubai and the Bloomingdales’s Christmas window displays in 2008.

In 2009 Amaya decided to return to Spain to concentrate on developing more personal work and bring the knowledge she acquired from her studies in New York to her home country. From 2009 to 2014 she offered figure drawing and painting instruction from her private atelier in Madrid as well as serving as an anatomy and drawing instructor at ESDIP (Escuela Superior de Dibujo Profesional). Amaya has taught workshops at the Museum of Navarra, Circulo de Bellas Artes of Madrid, The Janus Collaborative, and The Art Students League of New York among others.

In 2014 Amaya was invited to move back to the U.S. to take part in the creation of the first US branch of The Florence Academy of Art in Jersey City where she currently has a studio and teaches as a Principal Instructor. In 2016 she was an adjunct Professor at The New York Academy of Art.

Her work has exhibited internationally. Her paintings and drawings have been featured in American Artist Magazine, Fine Artist Connoisseur, American Painting Video Magazine and Juliette Aristides's book 'Lessons in Classical Drawing'. In 2013 Amaya was chosen as one of American Artist Magazine's '25 Artists of Tomorrow' in their 75 Greatest Artists of All Time issue.
