Using a pencil, begin with very simple shapes and strokes. Start by creating an oval and some quick lines to provide a basis for where his head and neck will be. Draw lines in the middle of where his face will be so that you'll know where to draw the eyes, nose, etc. This facial features line guide should go about halfway down the oval. Remember, for these early steps, it's best to keep your lines very light. This way you can erase and redraw them if need be.
Start fleshing out the shape of Savage's head. Give him more defined, rounded cheekbones, as well as a squared jaw. This is also a good time to draw in his ears and his eyes. To make him look menacing and evil, make sure his eyes are kind of squinted and narrow, and give him fierce, arched eyebrows. Draw his mouth, which should be a frown.
Add in a few details around the mouth, as well as Savage's nose. For the nose, place it halfway between the eyes and the mouth. Then add in some grimacing lines that go from the sides of his mouth up to his nostrils. These help show the expression that he's scowling. Add a few "scowl lines" under his lip. Again, make sure your pencil lines are very light. You don't want to make anything too final yet; you may still want to make a few changes to your sketch.
Draw his horns. He has two smaller ones on each side of his head, right by his ears, and then six larger ones protruding from his head like a crown. If something looks strange or out of place, this is the perfect time to go in, erase, and redraw it.
At this point, you should have a fairly complete sketch. If you want to give your drawing a clean, finished look, you can add inks over your pencil lines. This can be done with a variety of pens or markers. Just trace over the lines you want to keep, and when you're done (make sure you let your ink lines dry), go ahead and erase the pencil lines. This is also a great time to add in some smaller details, such as the texture lines on his horns, the pupils in his eyes, and a few more forehead creases to show his angry expression.
Even though this tutorial is really only focusing on Savage Opress' head, it looks nice to add in some of his collar area. Draw the lines that make up his shirt collar. And then you're ready to start finalizing this drawing.
Finally it's time to add the tattoos! Using a pencil first, shade in the areas, as shown in the picture, and keep them very light. Once they look right to you, you can darker the areas in with heavier pencil lines, or you can use grey markers. You just want to make sure his tats are dark, but not completely pitch black.
And there you have it -- your very own Savage Opress headshot drawing! You can color it, too, if you like. Here's a color version that I created digitally in Photoshop. You can use markers or crayons or whatever you prefer. However you decide to finish your drawing is completely up to you!
