Adding a subtle touch of smile to Jessica Henwick.

Inspired from a photograph.
I was looking for a two tone result so I just used one grey and one blue pencil.
The background was too neutral to my taste so I added lines (whose half is) parallel to the directions of lighting and of her eyes.

Filling up the red on the outfit before refining the eyes of Songlian, portrayed by Gong Li in Raise the Red Lantern directed by Zhang Yimou in 1991.

Drawn on an A6 sketchbook using four coloured pencils at a coffee terrace.

Ready to take off.

Probably a vagrant darter, also known as sympetrum vulgatum.

Helen Folasade Adu, lead singer of the band Sade.

Inspired from a photograph by Chris Roberts in 1990.

My idea was notably to highlight the strength of contrasts.
I just used
- a 4H graphite pencil,
- a twenty-five years old mechanical pencil whose lead (I suppose that) is a HB one and that I last used when I was a child,
- a stick of compressed charcoal.
