Botanical artist and illustrator Cristina Cilloniz unites two passions in her illustrated projects: nature and watercolors. She discovered the technique of negative watercolor painting through her constant search for new ways to recreate the beauty of plants and flowers, among other elements. This technique has enabled her to create a feeling of depth through the build-up of layers, and create illustrations that seem to jut out of the page, by giving special attention to the background in her compositions.

In this course, you will learn how to use the negative watercolor technique, with the use of natural elements. Starting from the initial creative illustration process, learn how to create a mood board, a color palette, and useful exercises to warm up the hand, until you have learned all you need to create your finished project.
