I don't show New Zealands, but I would say she is weak in the loin, hippy, and chopped in the hindquarters.
Every meat rabbit I've ever seen is built like a brick. You cannot see any weakness in their loin, and you definitely cannot see their pin bones.
I agree, she may be a little on the small side. At 8 mos old, she will probably show as an intermediate. You may get away with weight until she grows into a senior.
She has very lovely coloring but her coat is in bad, bad shape for showing.
If you want to show her, be sure to get her tattooed. Check her weight and age for the correct class she should be in. Check her toenails and make sure they are all there and they match.
As ottersatin said, a losing rabbit on one table can be a winning rabbit on another table on any given day, and the only thing price says is how badly the seller wanted to sell. It really is not a guarantee of quality.
