Wow. I’ve been doing cakes awhile, and I’m not even really sure where to start for this one. It looks like each tier is done in fondant, and then wrapped in a second piece that gets decorated with the scalloped edges. Those edges with the swirls look possibly either like royal icing stringwork or you could also mimic the look using gumpaste in an extruder tool. I’m not really sure about the rest of it though… it’s really complex.
You could try to reverse image search on google, to see if you can find the source of the photo (and also in turn the baker who made the cake) to see if it’s ok if you a) attempt to recreate the cake and b) if they say yes, ask for any tips they might have.
Good luck!
