I did mine a little differently by putting the lattice layer on the top of the card base.
I started by double embossing the top layer with Craft concepts -Budding Vine embossing folder and an oval scalloped nestability, then cut out the cente. It was then coloured with Luster Rub-ons Russet colour and my finger.
The butterfly is a Marianne Creatable which I purchased from FatCats.
The flowers I made by quilling.
