I don't know if this was discussed before here, but I want to know if anyone can achieve that.
Let me explain more, Can anyone draw a person (e.g. an old friend) with no reference at all?, And make the drawing exactly like him?
I can draw a realistic person with no reference at all, but a person who doesn't exist irl, What if I want to draw a friend that I don't see anymore and I don't have any picture of him, but i remember him very well in my memory.
Also if this is possible is it common?, or just a very few artists got to this level?
