One thing I don't think I will ever need to worry about is copy infringement for source images. I never seem to capture the photo I'm looking at when I draw. The drawing seems to take on a life of its own. So maybe you can guess who this is but trust me it looks nothing like the photo reference. Brush pen line with gouache color, with a bit of Photoshopy work, not much, just color and erasing here and there. No new pixels were created.
