Its hard to tell, as the dogs (first 3) IMO are not stacked correctly and the angle of the photo makes it hard aswell, The last photo looks to be the better stacked one of the dog, however again the angle of the photo makes it hard to look at the overall conformation of the dog.
Be interesting to hear other opinions as I am still learning aswell
