Osprey Pens - Pen Factory (color)

There's a phone in Graham's Up the Tree and kids will have no clue what they're looking at or how those "buttons" work.

This was drawn with a Japanese fountain pen, Japanese ink, and painted with Japanese watercolor. To be specific - I used Holbein watercolor and Platinum Carbon Black in a Pilot Falcon. This trio is perfect for me.

Drawn on my new iPad Pro using Procreate. This is quite an app.
