Here are a few pictures I took while making a 30×18 cm watercolor after one image of the graphic novel “Daytripper” by Fábio Moon & Gabriel Bá:
Pencil sketch
Wet blue wash and blue droplets over the masking gum
Several layers of blue wash to render the light underwater
Peeling off the masking gum. Unfortunately paper was peeled off as well.
Brown hulls of rowing boats, fish colours, ropes as well
Detailing the fish using a Pentel black brushpen
Final result with text in speech bubble
The watercolour is now cut and framed
