This is the creature that I created on Pablo Munoz Gomez's Zbrush Creature Workshop course.
The course was excellent and takes you through all the steps from concept through to final sculpt and render with loads of helpful tips along the way. I learned a load of new skill in Zbrush while following this course and Pablo's feedback was great.
All sculpted and rendered in Zbrush with final render passes composited in Affinity Photo.
