Watercolor on paper. Cold press surface, acid-free paper 140lb (300gsm). This painting is part of the study of light and shade on the face. Alex beautifully gives character to these identities by strategically adding color to their faces. There is a touch of sadness in the face in the light. And a touch of joy on her face in the shade. Meaning that emotions come in different shades and are usually combined. The painting is equipped with museum glass with an optimal light transmission that virtually eliminates reflections, blocks up to 99% of UV rays, and brightens colors. Great durability and easy cleaning. Color stability Guaranteed up to 100 years
