I am trying to sketch a picture of someone and I want to make a gradient like thing where I can get the lighting just right(the light is brightest on the right cheek and darkest at the left side of the face, light is radial and the brightest point is about 1oo% of the cheek and that's it) I want the gradient thing to match the lighting's position as I draw the skin, is there a way to make the pen do this? or should I use a gradient mask? What should I do? Picture: https://drive.google.com/file/d/1czar3i1Z_uy37BOfrGdo1wZf0HZBKJw2/view
Thank you for the help in advance.
