My Eye Sketch

Hello, I am micro97. I just started drawing a few weeks ago and I am here to show my progress.

As a newbie, I statred drawing lines, curves, circles, shapes and also studied basic shading using the resources I found online. My goal is to be able to do realistic portrait sketches, so I am practicing to draw basic parts of the face and I started by learning how to draw eyes. I have been practicing how to draw eyes for weeks and the image below shows my best eye sketch.

I learned how to draw eyes from Mmmmonexx, a south korean YouTuber and artist who draws semi-realistic portraits.

As a newbie in drawing, I'm sure that my sketch has some errors that I failed to recognize and fix. I'm aiming to improve and I'm open to criticisms about my sketch. Any tips, suggestions, and criticisms will be accepted. Thanks in advance!
