A note about references for my own conscience: I missed a couple in the included About file. For "Lover's Stones", a photograph I downloaded (from a site that afterward leaned into AI crap) to use on an older project helped me loosen up. The book 101 Textures in Colored Pencil by Denise J. Howard was my primary reference for the rusted steel.
