Winter pansies and Dusty millers are basic plants installed for some winter color. But the planting above is backwards. Dusty millers should get bushy as they mature and they will most likely obscure the pansies behind them. That's not what we want.
Proper planting demands pansies along the curb to allow for color viewing. Note: the pansy colors should have been mixed a bit. The line pictured above is all purple.
Dusty millers should go to the back. They are treated like annuals and replaced in spring. Some home gardeners keep them around.
Don't forget to dead head your pansies as the fall season progresses.
