Behind the transparency is crumpled foil.
On the video, she used an old book page to layer her ATC but I have used a vellum with pansies on it between the transparency and the foil to layer my ATC. I colored her wings with a white pen.
I colored the flower and leaves with alcohol inks.
This was not on the video but was another technique that I learned at a class I took at our local stamp store. I let a drop of each color dry in a plastic pallet and after it was dry I used an artist brush that was damped with blending solution to paint with.
