Step 2 - Add another two big oval shapes, this time the ovals are tilted a bit to the sides, if you are not sure about the position add some guidelines to help you out.
Step 3 - Add his eyes in the middle of the ovals we drew before, also the eyes are a little bit tilted.
Step 4 - Add more details to his eye, start with the eyebrow in just between the eyes and go up with a diagonal line.
Step 5 - Do the same in this step but this time the line is touching the eye, draw another one just above it.
Step 6 - Add more lines under his eyes to give the mask some wrinkles.
Step 7 - Draw the outlines of the mask, start with one side, around the same line of his eyes draw a curved line where his ear suppose to be. Do the same with the other side.
Step 8 - If you used a pencil, trace your guidelines with a black marker and erase them after.
Step 9 - For the coloring add a few bright spots at the top of the mask and around the eyes. You can follow the coloring technique I used in the video just up this page.
