I've named them mystic for the simple reason they are so complicated to make :))). The petals are made from 3 strips of paper: dark blue on the sides and light blue in the middle. With quilling it is a bit difficult to give the impression like there is shadow, but i've given a try by inserting some dark blue strips on the small flowers petals. I don't know if looks like there shadows but it makes a nice effect.
If you have a white empty wall, this painting will add some attitude to your room. And for a better effect you can use the background color of the painting to decorate the rest of the room.
