No problem! Let me show you directly. New Zealands have a commercial body type.
As you can see from these diagrams they're supposed to be very large and round. This translates into muscle mass, which is the part on a rabbit you eat. As you can imagine it's much worse to have a skinny rabbit like a full arch type for eating as almost all the calories will go into bones and organs not muscle. Almost all meat rabbits have the commercial body type. A few have semi-arch or compact.
The rabbit you posted is posed a bit weirdly, but not so badly it would distort the entire body. So just taking an outline from an example of what a commercial rabbit "should" look like and superimposing it over the picture;

We can see that it's got a REALLY low topline, especially in proportion to its head. Now
this doesn't mean it's a bad meat rabbit on its own. A rabbit like this may have other good traits, like an ability to raise bigger litters, or faster growing kits that outweighs its muscle to bone proportions. But that's a bit of a gamble and you should either be getting a good price or trust the person you're working with to represent the rabbits mothering abilities accurately. At $40 if I didn't care about breed, showing or selling kits for anything but pets I'd think about getting this rabbit exclusively because it's a large, proven, doe at a reasonable price. I would not breed this doe with the intention to sell as anything but meat or pets. No fairs, no 4H no market pens, none of that.
(To put price in perspective, someone tried to sell me an equally ugly proven doe this month for $120 because it was a purebred rex in a rare color. I did NOT buy it. I *was* willing to buy a nearly equally ugly doe kit from that breeder for $45 but it fell through. All around the interaction was bad vibes and wondering why their rabbits were so sketchy. A southern ohio breeder that helped found the NZ breed sells unproven 10 week bucks for $300. Local craigslist breeders sell unproven 10 week bucks for $10. So there's a scale there with a lot of variation based on quality and gender and proven or not.)
Now lets take a random picture of a "show quality" NZW from the internet. I chose this one;

You can see this rabbit has a LOT more muscle mass on it around the back and rear. Its head is proportionally smaller, and it fills out really well. This rabbit probably weighs more, and has more muscle to bone/organ ratio, which is good for eating.
But that doesn't mean it's a good meat rabbit for breeding. This rabbit may have smaller litters that grow slower. In fact that's a common problem for show-quality rabbits especially in other breeds (less so in NZ because they're still the most popular meat pen rabbit). But you can very clearly see that this rabbit has very good muscling and a much better shape. That body size is all meat, and that's something you can quantify without having to take someones word for it. So a rabbit like this will be more expensive, but will also be better in shows, meat pens, and looks better to a buyer.
There's more to assessing rabbit quality than this, the doe above may have other positive traits that would show up better if I saw it posed properly or could inspect it in person. Maybe it's even got a temperament I like. But as it is, I hope this helps start you on the path to assessing rabbit quality through photographs.
