Duplicate background layer and change to Multiply blending mode to intensify colors
Add PWL layer in soft light mode to darken background and
brighten the roses and red leaves.
Created a stamp visible layer and applied filter to remove
detail from the background. (I used Buzz simplifier) then
add layer mask to reveal the original detail of roses and red leaves.
Crop for printing (I did 2x3 proportion) with an "rule of thirds" to position the roses
