The lace is just cut outs using a mold. Then connected with frosting to make it look like lace. I'm not sure by the picture of what the shiny appearance is, but you can get luster dust, or pearl dust, shimmer dust, there are many options to get a shiny appearance. Also if you have a handheld steamer, it will make the fondant shiny.
You could get that effect by applying flower and leaf cut outs over buttercream or fondant.
You could use edible luster dust (dry or spray on) or airbrush it get it shiny first and then apply the flower & leaf appliques, joining them with royal icing piped with a #1 or #2 tip.
You can make your own custom pattern by using whatever variety of leaf and flower cutters you want.
