A pretty awesome tutorial covering how to do shading and detail work with Illustrator. Pretty tricky if you are low to moderate-low skill set in Illustrator, but a heck of a good challenge!
Today we are going to learn how to create this gas mask using only vectors. This is a really advanced tutorial, not only for the ones who are familiar with this software, but for the ones who are used to making traditional illustration too. I hope you learn a bit about depth, shading, hachures and other aspects involving this illustration, and, of course, have fun.
