I don’t know how many times I have to draw it

I don’t know how many times I have to draw it. Hundred? Two hundred? Three thousand? It costs, it costs and it costs. It never comes out the same. A slight variation in the nose or chin changes his expression and the character is no longer the same. On the other hand, it’s like it’s starting to be in my head and what’s wrong is the way I draw it. Like every time I draw it I was trying to portray from memory someone I remember.
No matter how much I try to structure it, any small variation changes it and it is when I free myself and do not structure it that it most resembles the image in my head. When the drawing comes out fresher.
