I’m not as good at judging Nubians as I am with Alpine, Lamanchas, and Nigerians but others will help soon. She looks healthy. I know you said you might not be able to get more pictures, but a helpful angle would be from the rear to see her width.
She looks like an awkward yearling to me. As she matures her back and rump should level some, but she’s probably never going to be stellar in those areas. Front end looks okay, with nice, clean, sharp withers, but her legs are too far forward and she doesn’t have good brisket extension. Good depth for a yearling. Legs and pasterns look like and strong.
