This is a very cute image, well done. Your colours seem to correspond nicely, and I don't think any one part of this image distracts from the overall quality of the piece.
When I zoomed in to take a look at the eyes (eyes are a very big pet peeve thing for me), I found that they were nicely shaped and look realistic - a big well done there
The most striking part of this (in my oppinion) would be the bunny hood - it's adorable I love how you've done the ears shaped differently, and pointing in different directions instead of having them both just pointing upwards or having them both hanging by the side. This definatly gives towards the cute factor of this piece and makes it a litte more interesting to look at. I like this.
I also love the tiny little pompoms on the tie to her hood/top, they are clean and look fluffy, I think you've portrayed this well. So well done. A very nice piece, and I look forward to seeing more of your work
