This white rose cascade is beginning to take shape pretty quickly. I already have two more open places that I'm going to insert roses in.
Following my rules for the flower face - you can see the center rose facing straight forward, the side rose facing tilt back and this new rose is tilted away from the center rose.
This bouquet is taking on a definite dome shape when seen from the side.
Place another rose on the right between the center and lateral roses.
Note that I didn't make this placement "perfect" - but it still balances out the opposite side.
