The mood of this image is very calming, I feel as if I should also be at her feet, taking a nap.
The colors you used are very pleasing, I love how you use subtle color undertones, like the pale yellow and dark magenta's.
The thing I like best about this is the consciousness you have of your line art and how it impacts the image as a whole. The way you go from black to a soft gray makes it pleasing to your eye and doesn't distract from the image as a whole.
If I were you have you change anything, it would be to add the same amount of gradient shading to your skin, as you do your hair.
The first thing that grabbed my attention to this was the background. While the girl herself the center attention, the amount of details given to the environment around her is really an eye catcher.
I'm a huge fan of how gradients were used in this. The most catching of the uses being in the hair, where it flows from a purple to a pink to match the skirt.
I would have liked to see more joint details in the feet and hands, and if RowneniiChan were to edit this, I would suggest that those be the details she give her attention to.
Overall every item in the image has a little bit of life to it with the use of color and shading.
