I'm a visual artist living in Cornwall, in the UK and working in collage and printmaking, drawing, painting, digital media and photography.
I love the depth, especially in the pale yellow areas. I'd love to hear about your process some time.
Claudia, it's just a lot of transparent layers, made with diluted acrylics and watercolour, the pale yellow is a quite watery acrylic gouache, so it's semi opaque. I hope that helps a bit ! :-)
