Also, I believe the orgin of the rabbit people thing is this legend: [link]
Several game companies and fantasy publishers have used imagery like this in recent years, with the origin being te moon-rabbit traditions (Note that I'm not saying you plagarized this from a game company or anything, just that that's one of the places the idea might've come from).
The red eyes are creepy, doubly so because everything else is so serene and peaceful. They're the kind of eyes I'd expect to see in a horror movie, and the way her face is sorta framed by the bushes and such makes me notice them right away.
Aside from the eyes, the level of detail here is amazing. I also like what you've done with the light, making everything in soft shadow.
ooh I really like the colors in this, and your lighting choices are very nice. The composition is also very flowing, calm and the stones complete the cirle and bring the attention right to her. The only thing I'd say is that those stones need a little more love, they don't look solid because they're a little rougher than the rest of the scene and right next to her dress they really stand out. If only the Na'Vi in Avatar looked like her!
