On the day of the photo when I woke up my hair and beard looked crazy so I took a mirror selfie.
Later on I traced the image onto thin notepad paper. I taped the paper to my phone to keep it steady and turned the phone's brightness way up so that the image was visible through the paper.
After it was done I took pictures of the drawing.
Today I imported one of the photos into excalidraw and traced over it with the drawing tool.
