The bunny is busy enough without a busy background when you're taking photos later. Solid colors are generally far better for backdrops unless you're going with a theme. And then the pattern should be simple.
Because she's in the shadow and not in focus it makes her very muddy. And when I say not in focus, let your eyes go to the edges of her outline. It's soft and not crips. I think the zoom was pushed a bit too far.
Perfection.
...too close. A little further back would have made it better...
The Orp? I'd guess English based on the looseness of the feathering, but I wouldn't say one way or the other until she's at least six months and looks like this.
