The debris around the tires looks a bit unnatural...it would conform more to their shape. And the rust texture is pretty convincing on the metal, but it shouldn't be on the tires.

I see another author also saw the source in a similar way and created a tractor style vehicle also. It's not that unusual and it's interesting to see how another author interprets their version. Even though the basic idea is similar each entry is totally different. Good luck to both!

I like that the way you fixed the trees reflection in the windows was to break all the windows out! Creative idea.

Well done and imaginative. I cannot see any marginal lines, everything blends well. Wonderful, just wonderful.
