Unfortunately, this was one of the older references saved onto my hard drive and I have since lost the author information. I would like to credit the artist and I believe I found this one somewhere on DeviantArt. I have tried to search for it on there, but I couldn’t get it to appear in the results. If anyone knows who the artist is, please let me know!
This tutorial focuses more on ‘drawing’ both eyes, instead of just one and have the other one ugly or too distorted. This is not about painting eyes, though I have small tips about it at the end of the video.
