How I sketch multiple characters (Patreon)

I was starting one drawing these days and I realized I never showed this part of my drawings before. These are the first 3 layers combined, and I found them more interesting than just showing each separetely.

The idea is that I make literal stick figures just to test the idea, and then I sketch out the volumes like the characters are simple robots. Granted, I skip some parts sometimes, like breasts and the hipbone because I'm never quite sure how big I want them.

Then, in this particular sketch, I used two colors for each of the characters, so I can more clearly visualize where each bodypart is. The last layer is incomplete, but is a simple black outline to see if the figure works how I want it.

By the way, anyone guess who they are?
