A tumbleweed soft on the roadsoft doesn't seem to have any contextual meaning that I can find.Loose?free?blown? Help or change?
I was, when that old shack of his showedIs the appearence of the shack conditional on anything? It seems as though the shack moved into view unaided and independently. As "showed" is not part of the rhyme scheme perhaps "....when his old shack came into my view."
behind those enormous old pines those pines? As distinct from the other pines? I can tell you can "see" your picture but we as yet, cannot. Try "some"
it sat where the old river winds.unrelated "it" makes this line disconnect very abruptly. I cannot readily suggest a construct to get you re-attached unless "on the banks where the old river winds" would suffice. Comma after "pines," to link the descriptive continuation.

A shotgun was close by his hand
when I stepped one foot on his land,maybe "set one foot" to make the action consequentially dangerous. "Stepped one foot" is gramatically ungainly to a degree, anyway.
he thought that I meant him no harm,A capital letter here would help to demark the characters. After all, he had the gun. so maybe "He thought I could do him no harm"
invited me inside to warm. "So he asked me inside, to warm"

So where are you coming from, Son?”
“Just passin' through. Are you done?”unnatural narrative but enough from me
He stood up and belched out guffaws,this man is obviously a psycopathic maniac with autism who dies not relate to his environment. I mean what is so funny? Needs more thought.
said he had once run with outlaws.One has to ask, why mention it?[b]

His face hinted that he must knowI just know I amgoing to get lost so see end[b]
and no one could knowingly know.
He wanted my trust way too much
so my hand shied away from his touch.

I spied his guitar on the floor,
When I first walked through his front door.
I felt of it's strings with my nails
and soaked up the wondrous details.

He guarded the beans as I sat.
The chat rather quickly fell flat.
As quick, I was out of my chair,
he tended the food with a stare.

I aimed it away from the stove
so blood went away when I drove
the old box guitar through his face-
don't want all the food here to waste.

As soon as I'd eaten, I ran
as fast as a guilty man can.
The taste of his skin on my lips
and the flesh of his bone in my ribs.

Telling a story is not easy at the best of times. First you must know where you are going. This sounds as if the story ran away and you couldn't keep up. I admire you for your efforts but believe me, you bit off a whole lot more than was chewable. I will only add to this IF you believe it would help.
Best,
