Nice clouds and colors..you should sharpen up the horizon line and put in some sharper details in the hills , maybe some flowers? This could be very nice

You did a pretty nice job.
It could be less blurry though.
What I do, and Its a lot of work, is I go use a straight line and go acroos for every single color.
I think thats what xod uses on his awesome backgrounds.

Yes, this looks like a good basis for something.. flowers, a horse, some other animal, a fence... something.
