Start by drawing out your basic shape. I chose an angular brow shape. If you want a tutorial on how to draw the eye shown, please see my other guides.
Next, fill in the brow with long, swift strokes to look like hair.
Then, add extra shading along the outline of the brow to give it definition.
Next, as mentioned in the video, erase a bit of the center of the eyebrow and blend with your finger to add shape to the brow.
Finally, shade underneath the brow to show the shape of the eye socket. Most people forget to do this, but it helps so much to make a face look realistic.
Now you're done! Please check out my other guides, including a tutorial on the eye, and give me a heart or follow me f you like what you see! Thanks!
