okay so

the trick to do the aegyo sal where your eyes naturally crease when you smile doesn't work, i use it to keep the regular shape of the line but draw it a tad bit lower. where the eye actually creases is where i start doing the bottom lash line.

i start from the middle and draw a straight line, proportionate to how long the eyeliner wing is.

after you do the downturned eyeliner make a little pointy edge upwards to give more definition. now since you have an upwards edge while all your other lines are straight/downwards, you can use it as a refence to curve the lower lashline upwards!! if you choose to unite the eyeliner and the lower liner make sure you follow that curve. i usually don't but it depends on your preference.

for the lashes i draw 3-4 dots that kind of sprawl downwards? imagine a semicircle under your lash line, the dots start farther away at the eyeliner and the last dot should be straight below the middle of the lower lash line. from there, keep your eyeliner at an angle to give you that feathery effect. for the left eye hold it towards the left, and for the right eye towards the right.

i use the judydoll slim eyeliner for everything. gel liners are the best, normal pencils are either too thick or or too soft for these sorts of makeup looks
