Bouquets I Love: Thoughts?

After spending weeks looking online, studying what flowers are available in October, I have fallen in love with these bouquets. My dress is ivory, and Jen's is expresso, though there's lots of flexibility here in our accent colors.

However, I know I'm in love with hypericum berries, roses, ranunculuses, white freesias, lilacs, viburnums, alchemilla, sweet pea, silver dusty miller, and green hydrangeas. But above all, I'm in love with rustic, natural, clean. Thoughts? What would work best with my dress and our venue?
