Hi Emad – I’m sorry to read that you’re frustrated but trust me: You’re in good company! Everyone starts out being disappointed at first but you can only improve from here. Believable human faces are notoriously among the most difficult tasks in all of computer graphics. It’s going to be difficult and it’s going to require practice, but you WILL get better at it 👍
I’d like to look at your sculpts to give some feedback but I don’t see any. Can you link me to where they are or post some screenshots here?
