In this video I show how to draw a BISON SKULL using a pen. Skulls are always fun for me and great for practicing shading in order to show the form and shape of the white bones. I use a lot of crosshatching but I actually prefer using random doodling lines when trying to get various shades of tone. Experiment and see what you like but definitely try different techniques! I will also shade this drawing using a pencil in a separate video so please check that out! Thanks as always for watching and your support, and have a great day!
