More detailed facial sketch
I establish the light source as coming from the top left of the image. Setting it helps me create light and shadows on the character’s face and also designates where the shadows should fall. Here I use my horizontal canvas flip custom shortcut (Ctrl+ Q) so I can accurately draw the face and its proportions. Flipping the image makes it easier to find mistakes after you’ve been staring at it for too long. Up until now and throughout this step I use the Soft Round Pressure Opacity brush (Brush Opacity: 100 per cent, Flow: 58 per cent).
