A background would really help. White is just too dominating for your chop. I would even try to make it sitting with a reflected surface and maybe a shadow. If you go that route with the shadow, off-center the rabbit more.

Very nice idea author,but its to flat for my taste...try to give more round-es using dodge and burn tool and create some shadow for the bunny...also edges are to sharp,make them a bit softer using blur tool...good luck

I have made some changes

Awww too cute ! Well done

Author, now it's just a cardboard cutout against a background...you need to integrate the bunny with the background...this could be really good!

nice ........... all the best ..........
