Margarida Esteves is an illustrator, living and working in London. Although she enjoys very much working digitally, pencils and crayons are her all-time favourites. She always carries her sketchbook, where she doodles new ideas. Her work is colourful, layered, textured and detailed. She gets easily inspired by people, films, photography, vintage illustration and history. When she's not working or drawing in her sketchbook, she enjoys developing small personal projects that usually involve printmaking, embroidery, lego and miniature models. She also collects children's books and interesting illustrated packaging.
