I'm guessing you'd like a bit of feedback. Your choice of background is OK. If you do more of this, move the rabbit a little futher forward, away from the background. This will give the image more depth. Frame the rabbit so you have a little more room around to ease the crowded look. Your centering is fine.
If you have a addition lighting, you could bring out the texture of the fur. I suspect though that you would have done that if you have it.
