Now for the eyebrows and pupils!
Levi wouldn't be complete without his signature eyebrow furrow!
Start the left eyebrow just above the top eye guideline, and let it dip down so it's just barely touching the eye, before slanting it up again. It should end with a little, subtle downwards slant.
The right eyebrow should start one again, above the guideline, and arc downwards towards his eye.
Add the furrow between his eyebrows, with two little winkles close to them.
Draw two circles for his pupils, they should take up about 2/3 to 3/4 of the space. Make him looking up, because I can't imagine anyone being shorter than him ;)
