Stained glass de-structured

My first version of stained glass engraved in the slate having been very popular (once shown to the public, it was only 3 days in my company before someone bought it), I decided to make another one, more ambitious and this time using the same method as for the backrest of my seat, ie, by de-structuring the stained glass pattern.
Here is a draft in progress on paper, the concept seems valid to me, all that remains is to engrave the slate.

It took me more than a year to make the first one, this one is three times bigger, you will have to wait a long time before you see the outcome :-)
