Step 1: Draw the wire frame of character to identify the body parts. Because this is an old witch, she will have quite short legs and a hunchback :D
Step 2: Draw the face based on the previous sketch. Note that the witch often has a protruding chin, a wide mouth with very few or no teeth. Remember to draw a hooked nose, add some warts if you like :))
Step 3: Draw the witch's hat. There are a lot of designs on the internet, here I only use the most typical one - pointed hat.
Step 4: Draw the hair. You can illustrate a witch with long, curly hair as in the picture, or create something new, for example long tangled or stiff hair...
Step 5: Draw the dress of witch. An old witch often wears an iconic long robe with a ragged dress. So draw zig-zaggy, letter ‘M’ shape at the bottom of the costume =)))))
Step 6: Draw the legs and arms based on the previous sketch, just pay attention to draw them reasonably =)))
Step 7: Draw the broom. This houseware is very popular in our life, so you can draw it as you like or search for reference, but I don't know how to describe them :)))))
Step 8: Erase the sketch. Just leave the drawn lineart part.
Step 9: Full color as you like, or as shown in the avatar at the beginning of tutorial. If you want a spooky witch silhouette, draw a large yellow moon as the background, then fill the witch and broom with dark color!
That's it =)))) Wish everyone success and a happy halloween season :>
