I only lined my upper eye in a winged shape. The result is that the eye look longer. But at the same time, the eye looks narrower.
On this eye, I drew the eyeliner downwards to meet the bottom liner. This makes my eye look a bit rounder and bigger.
This is what the two eyes looked like zoomed out. You can see that there's quite a big difference. Although my two eyes are different in shape naturally.
*please excuse the random splotch on my cheek, I was testing some blushes :( *
