A small sketch in pen, with water colors, of Roy,
This is my favorite technique for my sketchbook. This is pretty fast so good for work-on-the-go. I don’t have too much bulky stuff in my travel gear, and you still have precision and colour. Of course you can also work just in pen or water colours, but this is fast and it looks good.
At least that’s how I think about it.
In this case I used a drawing pen. The Sakura Pigma Micron 03 in black. These have been favorite pens for years. I have them in black and sepia. Very reliable and water proof. So you can add a water colour wash.
The water colours are my trusted Winsor and Newton watercolor set, the same one I have been lugging around with me for 20 years now!
