Hi Gregory Peony, 

Thank you for the feedback and sharing your interpretation. I noticed that you used a custom imagery source (https://wayback.maptiles.arcgis.com/arcgis/rest/services/world_imagery/wmts/1.0.0/default028mm/mapserver/tile/20337/{zoom}/{y}/{x}), which I’m currently unable to access. Can you let me know if it contains more up-to-date imagery and how to access, so I can make sure to keep this resource handy for my future edits.
