This tutorial can be useful if you wanna learn to draw Jon, or draw a similar looking character

Fist what you wanna do is draw an oval

Next you gotta draw another oval but it,'s not a whole oval since it goes behind the other eye

Next you need to draw two smaller black ovals inside the eyes, for pupils

Next you draw a line that looks like it comes out of the right eye to start the head

Hen you gotta draw a curved line with a bump at the top, for an ear

Next you draw one bump on the side of his head, and 3 bumps on the top

Next you need to draw some bumps on the back of his head, for the back of his hair

Then you want to draw a bump on the top of his head to start the top of the hair

Then you need to draw one small hair and 3 bigger hairs

Then you give him a mouth with a slight overbite and a straight line for a nose

Then you just gotta draw two lines for eyelids, two rectangles for a collar, and two lines for a body

You can draw him with a different facial expression if you want, I think I drew him better in the thumbnail
