Changes with Photoshop:
I used the Chanel mixer to make it look more green.
Then I used the pop to make the flower look reddish or pink, contrary to the sky.
I also used curves to change the tone of the image, made certain parts clearer or lighter.
I used a little "burn" at the top right corner of the sky.
Finally I used the brightness and saturation to adjust the overall effect of the image.
Great photo to begin with. I like the edited also, the colors are very calming. The two colors work very well with other, neither of them are over powering the other.
