The first image is the original image of a beauty forest I took from internet.

With the first design, I used Replace Color tool in Photoshop and changed the green grass on the land to red color and it looked like a carpet of red flower. Then I also changed the green leaf to orange color. Now, with the whole image, the forest is in summer season.

The second design is an opposite with the first one. With the help of Filter Render tool, the forest looked dark, like after a burning.
