Hi friend! To be honest, i think the rendering overall looks really nice and matches perfectly fine, the face could just use a teeny bit of contrast. So i added some minor highlights and shadows to do that, but i wouldn’t add much more as it reads beautifully as is. Most changes i made were anatomy-wise, mostly from the chin to the nose. The “average” side profile for people is a straight line from the tip of the nose to the chin, with a small gap between both the lower and upper lip. Of course that doesn’t go for everyone, but especially with more anime/manwha esque styles like yours the artists tend to stick closer to these proportions. For the eye, remember that it is a sphere and think of how the eyeball looks from the side having a sphere in mind. I ronded the iris as well as the eyeball itself off slightly and show the inner corner slightly peeking in from the side as well. It is a really nice drawing already, good luck and most importantly have fun!
