Good evening. I started learning drawing in the dry pen by searching and watching lessons on #YouTube until I reached the secret of drawing with ballpoint pens. Time and focus determine when you make mistakes and when you succeed.
The most difficult detail was the gradation with color and deception, you have to be very precise, because any small mistake means re-painting from the beginning.
I used :
-White paper
-dry blue pen
-and my patience haha
