I'm curious how to draw a sharp eye look with eyeliner.
The thickness of the eyeliner varies every time I draw it, so the look changes every time.
I found drawing a natural wing of the eyeliner the hardest part, especially.
I also want to know which is easier for beginners among pencil, liquid, and gel eyeliners.
What are some tips for keeping eyeliner from smudging?
I'm also struggling to find an eyeliner color that suits my daily makeup.
I've heard that just drawing eyeliner well makes your eyes look much more defined, so I want to learn how to do it properly.
If I practice well, will it take less time to draw eyeliner?
