The original listing looks fine...just update the text/specs. Even though the image is of a digital mockup, it's still good. And if the panel change is significant enough, just do a front-on photo and drop it into the original listing.
Damned interesting module, btw...ARM based AND cheap? You oughta go talk to Robert over at AE; they did a collaborative with Dove Audio, and this might be a nice fit under the MDF, too! https://www.tangiblewaves.com/
