Field of stars

I'll start this critique by describing the atmosphere and impact it had on me as a whole:

She has an innocent and slightly anxious expression which fits perfectly with her perked up ears and the fact she's sitting alone at night.
Her tail curled up by one side adds to the innocence as it implies a defensive or pensive pose.

Having those blue streaks and a little "lick" of hair gives her character and individuality without being over the top.
Likewise, the flower and patterns of her ears and tail have a nicely balanced amount of detail.

The use of various hues of blue is great, everything works together whilst still having enough difference in colour for the fore and background to be separate.

The grass looks a little too fine for the rest of the image and needs more tone, and her ankle is slightly too pink.

Overall, a sweet and atmospheric picture, the "banner" of sky is a really effective technique.
