I love the softness that the yellow flowers bring to the look.

I created a quick inspiration board to incorporate your newest sample.  I envisioned a light filled, hazy sunset with all the golden colors coming alive!  Fresh poppies are painted in the field to give a nice splash of red!

I stayed quite neutral with the paper choices but really added a variety of colors in the tree.  Loving the sunflowers at the base of the tree!
