Check out this two-volume tutorial on character design by the Gnomon Workshop.
The Gnomon Workshop has launched Introduction to Creature Design, a new series of tutorials on professional creature design workflows recorded by Lost In Space Сoncept Artist Kyle Brown.
The tutorial consists of 2 parts. The first part focuses on the use of digital sketching to explore ideas, refining early concepts into a finished creature design. Kyle shows the importance of using references to serve as a spark for a new design, inspiring new shapes while always rooting design decisions in real-world anatomy and physiology.
The second part is dedicated to coloring creature concepts in Photoshop. Taking the initial concepts, Kyle puts them to work to show how to apply color and texture to designs.
