First thing you want to do is draw the eyebrows, and then you can finish sketching out the eyes, like you see here. Color in the pupils, and make sure you leave a piece of white behind for the gloss effect. Draw the cheek detailing and then draw in his mouth. Next sketch out the collar for his chibi sweater, and then draw his arms which are crossed over each other. I chose an outfit that he is seen in most of the time, which is a sweater or hoodie, and jeans. Add some detailing to the sweater and then move to the next step.
