Here is my attempt at that style, I decided to dust off a few older Hero Arts stamps and have a play.
I started by stamping and embossing in black the silhouette grass stamp, I then made a mask for the sun and distressed with lots of Barn Door, Spiced Marmalade and Forest Moss ink. Then I removed the mask and gently applied Scattered straw ink to the sun.
For the poppies I stamped and embossed in black again on some bright red card, I cut out the poppies and added the seed beads. The butterflies are stamped and embossed on vellum.
