Description: Before we start drawing, let's see which are the main differences between two similiar Corvids: crow and raven.
Ravens are lager and bulkier than crows, the beak of the raven is large and it curves close to the end while the beak of the crow looks thinner. Notice also the long and shaggy feathers on the raven's throat.
Description: Now it's time to draw the beak, it's very important to draw it correctly because it will make your drawing look like a raven and not like a random bird. Do not make it too thin but neither too thick. Looking at photos is helpful. Do not forget to draw the feathers above the beak.
