Step by Step
I am continuing to use the prisma colour soft core pencils in this drawing. I used the x-acto blade to help scratch out the light areas along the wrinkles and I also used the blade to help pull out the small details for the skin pores around the mouth. Remember, do not apply to much pressure onto the paper as you will go through it. Hold the blade at around a 45 degree angle and carefully scratch the wax pencil off the surface.
Any questions please ask below!
