I think you have the right idea. We need to have a way to get the path to really stand out if that is to be the primary subject - or, as you suggest, put a primary subject on the path.
Given the scope of the composition, my guess is that you would need something with more presence than a raccoon - perhaps a horse and rider?
Or maybe young couple strolling down the path holding hands and very much in love?
An old man with his soft grey sweater, weather-beaten hat, cane, and his faithful dog?
A little boy on the side of the path taking a leak in the bushes with his puppy beside him, head cocked to one side?
There's got to be something that will make you happy!
