An adorable rabbit!! *insanely happy grin* How did you get the lighting so airy? So pretty, again! I also love how you managed to fit in your watermark/username without detracting from the quality of the photo! Again, so awesome!!!
I can't use the critique feature, so I'll just give you my opinions...
This is the first thing that caught my eye when I started scrolling around newest/most popular deviations this morning. I used to have a dutch, about the same color this one appears in the picture, and I admit I love rabbits.
You've caught her (or him?) at a perfect moment, looking inquisitive and very expressive - relaxed, but ready to binky at a moment's notice. I like the colors, and the way the whites of the background, the rabbit and the clock are all slightly different: Even in the thumbnail on the front page, I could see the distinctions among all the elements and still get the impression of blocks of color (ears/face and clock face) against an all white background.
It took me a moment to get the clock/rabbit/timekeeper/Alice in Wonderland connection, but I think that's because I don't think in AiW, and not because it's not clearly communicated in the picture. Having now looked at a few of your other pictures, it's obvious (d'oh!) and I have to say I like your "real world" interpretations of the visual concepts Alice has to offer. Different and engaging without going the American McGee route. (Not that there is anything wrong with that!)
