Origami Lily of the Valley

The third origami flower I've chosen to work on, from Anca Oprea's book Beautiful Origami Flowers: 23 Blooms to Fold, is the lily of the valley.
To start off Oprea says to fold the paper like if you were making a square base, but don't make the base (43).

This advice helps me because I now know to just make the correct folds for the base, but I shouldn't jump ahead and make a square base. Continuing to follow the directions I fold in all the corners and then make a square base. I fold in the side corners in on both sides and glue them. Oprea says to "Allow the glue to dry" (43).

This is important for me because sometimes I'm not patient enough to let the glue fully dry so I reminder is helpful for me.
Next, I curl back the tips of each petal and open up the flower.

Any other ideas of what other colors I could use to make this flower?
