@-Solembum- Okay.
1. Muzzle is a little short. Canine muzzles are longer.
2. Neck is a bit short. Lengthen it some.
3. More of a chest needed.
4. Back is off some. It curves and drops somewhat awkwardly. Also, with the belly, you've got the tuck up wrong. It shouldn't go down near the back legs, it should be deepest in the chest area. Some dogs have more prominent tuck up than others. Labs, for example, have a fairly small tuck up, while Borzois have a very large one.
5. The back leg anatomy is off. It's very hard to explain in words for me, so take a look at this picture:
xxThe Femur, Tibia, and Fibula are too short and tucked back. The should be extended frontwards more. The metatarsus area needs to be shorter, and by making the Femur, Tibia, and Fibula longer, it should come naturally.
6. Last thing, the front leg is bent somewhat awkwardly. Look at the picture above for ref.
