Very sweet! You managed to catch this rat in a very engaging pose, and the brightness of her eyes immediately draws my attention, especially in contrast to the light colors of the rest of her body and the background. Her pricked-up whiskers and ears seem to be saying that she's interested in you, and it certainly did the trick to get me interested in her.
The light background and feather in the foreground are actually really nice artistic choices. They blend very nicely with her coat, and give the whole shot a softness that complements her cuteness.
Keep making these. The world needs to know how adorable rats really are!
