Sketchbook Illustration for Collecting Ideas
A course by Catalina Bu , Illustrator

Learn how to create detailed illustrations by experimenting and revealing your ideas
Learning to express your ideas through illustrations is like learning a new language, but with your hands: every stroke, line, or color is a personal expression of your creativity. With just a sketchbook of references and some exercises for practice, you can master the language of drawing with the illustrator Catalina Bustos Mendoza, better known on social media as Catalina Bu.
This course teaches you how to turn your sketchbook into an idea factory for creating stunning illustrations. Catalina walks you through the creative process step by step to help you understand how important it is for overcoming mental blocks and putting your vision of the world down on paper.

No entiendo por qué en la edición de los videos de las lecciones cortan tanto los procesos que realiza la profesora. Todo es cámara rápida y cortes! Por favor Domestika no se ahorren segundos en los videos, muestren los procesos completos, esa es la parte más interesante.
