Doesn't really look like Decay, since the lawn is obviously kept up, and whatsuch. I would recoment a diferent persepctive than just head on as well.
I hope you don't mind, but I took a moment to make some quickie adjustments. Consider the source though.... I'm neither an artist or a photographer.
I cropped out most of the image, and cloned in some grass to make it look more overrun....
Or you could go with a B&W conversion.
Just some food for thought. But all things considered, if it were me, I would go for a more unique perspective. Get down on the ground, or in the Jeep or something......Take 40 different shots, then pick your favorite.
EDIT.... you beat me to it with the picture you posted above this so it seems you took a bunch of shots...... but it seems really oversaturated. That aside, I like them.
