I understood lots and lots of details with this project. After going through sculpting individual parts of the face for practice, I had the urge to try a full face quickly. Little did I know, I had to waste loads of time on the hair and retopology and slowest ever viewport... Learned a lot about retopology and how should I practice more and more. Oh, and a lot about texturing and how to achieve a hyper-realistic look (obviously I didn't but I know how to proceed).
I got extremely tired of the hairs due to the terrible topology I had. So just let go of the eyelashes. In the end, the project that was supposed to be a sculpting practice turned into much more for me. Overall; eye-opening project.
