This is an excellent shot. The timing used to capture this moment is perfect, and the focal range is spot on as well. I believe you chose an good overall tone. The color is soft and light. It's even across the whole frame even blends well into the exterior, which actually contains some nice soft bokeh in it. Emotionally this picture is instantly draws you in, you can truly believe the bunny is hiding his face away from the camera. I have see other pictures of animals looking cute, trying to hide or cover their face, but not as well done as this!
The lighting and angle are perfect for your subject. The way your subject is covering part of its face made your name for the picture understandable. The timing for this picture is perfect. Blur in the background helps pop out the subject and the colors for it match the subject very well.
The way everything as been done with the colors and the expression on the subject is what drawn my into it. Tones for a picture like this are hard to find that go well with the subject. You did a wonderful job.
