FWIW, photo engraving is an art to do really well. it takes some practice and there is a learning curve to understanding what you’re going to get in the material. in what the image needs to be edited to look like as well as the settings and how each material will react. it’s always worth taking a tiny piece of a detailed section and testing that on your material first to see what you’ll get and then make adjustments based on that. much faster (and less expensive) than engraving the entire thing and feeling like you need to adjust.
