She looks seriously overweight to me. There seems to be a lot of fat near the back end, and she either has a very large dewlap or a few rolls of fat under her chin, if she has been bred from then it's possibly a bit of both I suppose.
I'm not an expert though, I may just be seeing a slightly chunky bunny, but I would be worried about her weight, she doesn't look a comfortable size if you understand what I mean.
