I love making digital drawings that look as much like drawing in a sketchbook with analog materials as possible. Georg Graf Von Westphalen’s ballpointy brush is the best ballpoint pen brush I’ve come across for Procreate. This portrait of Lake from the Museum by Sktchy app was drawn with the ballpointy brush using a colour palette I created from my favourite Bic 4-colour ballpoints. I love how it turned out, especially the hair.
