I am no expert nor do I show but I can tell you from what have learned. That first pup that is pictured stacked looks pretty nice. His coat looks nice, he seems to have a nice topline , although it looks like you are a bit new to stacking, his ear set is a bit wide but there are plenty of wide earsets in the show ring. The other two , the first one seems to have very nice true silk coat but I can comment on his structure is he isn't show stacked and the same applies to the pup in the last picture.
