Ortega Lerias is a figurative artist working in a variety of mediums on paper. Successfully using mixed media demands a huge amount of knowledge and skill. As the term would imply a variety of mediums are applied to the same ground to create one image. This means that each medium must be practiced individually to gain full understanding of its natural characteristics and qualities. It then must be carefully considered before combining it with another. If like Ortega the artist has a good insight into the materials involved, then some creative and innovative results can be achieved.
