I copied this from a photo on wikipedia. What’s the point of copying things from photos?
1. It forces you to look at the photo much more closely than you would otherwise, helping you remember what stuff looks like.
2. It gives you lots of practice in rendering a range of tonal values in whatever medium you’re using.
3. It gives you a simpllified, stylised image, compared to the original photo, which is handy if you’re then going to go and do something else with it like incorporating it into a finished illustration or osmething.
Okay, but what’s the point of posting drawings from photos on social media?
1. I don’t know.

This is me experimenting with drawing in red, blue and black biro. Because red and blue are at opposite ends of the visible spectrum one should in theory be able to suggest a pretty wide range of colour. This has some similarity to drawing “a trois crayons”, which is the art-history term for drawing on tinted paper in red, white and black.
Also, if I got a green biro I should be able to do RGB optical colour mixing like the painter Chuck Close.
