Remember, FOUR correct answers decide the winner. Good luck. Jim
That actually makes more sense as I had found four and was trying to figure out if two were connected or separate changes.
Here' goes my hat into the ring:
#1.) In the center of the diorama, just above the tracks,m there is a tree. To the left of this tree there is a rock. Above this rock, in Photo two, a tree has been added. It appears to be a mostly naked tree, and in photo two, it is clearly visible.
#2.) In the lower left of the diorama, there is a rock. In Photo two, this rock appears to have been rotated 90 degrees clockwise.
#3.) To the 11:00 position of the rock mentioned in #2 (lower left of the diorama), there is a tree (second tree from the left on this side of the tracks). In Photo two, this three has been rotated counter clockwise so the bulk of it's plumage hangs towards the tracks rather than to the right.
#4.) This was probably the toughest and could be a wrong answer. Once again we are on the lower left of the diorama. Start at the big rock on the lower left and look to it's 2:00 (roughly) position. There is a bit of a wispy bush in photo one that obscures part of the track. In Photo two, this bush has been greatly reduced in size to a mere shadow if it's former self. About half the size, I would say.
There goes. I could be wrong, but that's what I see.
