Here is a piece I started sketching traditionally. Then I inked and coloured digitally on Procreate, using brushes and a colour palette from True Grit Texture. I also did a second version using the screen tone textures from True Grit, go give a pop-art or vintage comics look.

However, I started this drawing because I wanted to experiment and practice more with Posca pens. So I transfer the image into a 250 gsm Canson Bristol board and painted it with acrylic pens.

I tried to keep the colours as close as possible in both versions, considering the difference between the colour palettes.
