Clear rainbow sky

This is my first Photoshop image,that I`ve used gradient tool many times.The sky came out perfectly and on the bottom right,you will see a small hill and a small river.On the left you'll see a bright ray of sunlight that made a rainbow.
I also have the rainy sky version of this right here -> tasmia-tasin.deviantart.com/ar…

Thanks to `s tutorial for the background,because of his tutorial I`ve discovered this image.
Thank you very much ~Ray3000
