I haven't critiqued in a while, and honestly I feel a bit rusty. However I REALLY love your Zefra and figured I could at least tell you my opinion. The usual disclaimer: I'm still new at this and may not be accurate.
Lovely feminine head with awesome pigmentation. Actually, her pigmentation throughout is absolutely stunning. She's a gorgeous dog! I really like how her neck is set on her shoulders. It flows well and looks substantial.
that her withers are slightly behind her elbow, but it certainly doesn't appear to throw off her balance. She looks very balanced and very athletic! Shoulder angle is very good, but humerus is short. You can see the pasterns in the lower stack pic, and they look nice. I can't really tell if the wither is flat or not, to be honest. This is not an area I feel super comfortable. I think the wither is flat since I think the top of the scapula is behind the elbow. Sometimes though I see critique threads where I think the dog has flat withers, and then more seasoned critiquers note of the "excellent" withers... so, who knows.
I also like the topline much better in the first (slightly stretched) stack. I like the slight slope of the back and this also shows her croup better. The croup is a nice angle, but I think it's slightly short. The stretched stack allows it to appear a bit longer. Her back end screams balance, in my opinion. Femur and fibula/tibia appear to be the same length- both slightly longer than the croup, and the fibula/tibia angle mirrors the croup angle in the lower stacked photo. In other words, the rear forms a nice parallelogram that structural diagrams like that of Linda Shaw
Overall, I like her size, her weight, her gorgeous coat, and her expression. She looks athletic and balanced. I admit that I have
looked up Wild Wings before on account of your pup!
