As Shawn points out, the trees surrounding Tigger's Barn go from green and lush to winter dead in a short space of time, this was because of the large gap in shooting between the rest of the film and the last scene.
The times on the boards at North Queensferry station are all over the place.
The shadow of the camera and microphone are just about visible during the POV shot of Shawn talking to T-Bone in the final scene.
A copy on the script can be seen sitting on the ground when T-Bone is explaining about animals going for the eyeballs on dead bodies.
