Fernando is a freelance illustrator from Valencia, Spain. He graduated in Media and Audiovisial Communication, but drawing is what he enjoys the most. It connects him with his childhood, when there were no big worries. He works mainly digitally and he likes using limited but colorful palettes. His illustrations are inspired from infancy memories, traveling experiences, 80's cartoons, and music...

When he is not drawing he enjoys reading, watching movies or hiking.
