Drawing a realistic eye( takes 2 hours)

Today I will show you my art with you. I have made a realistic eye sketch. It is not that easy to make a sketch like this. It takes time. I took almost 2 hours to make this. Well, I am not that professional but I am doing my best and one day I will be a professional sketch artist.

This is the final sketch. Hope you like it.

I started from here and you can see the below pick step by step. It is fun to draw. Drawing eyes is a little hard in a male or female face sketch. I hope you guys will like my work. If you have any suggestions, please feel free to comment below.
