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.
Thank you so much for the critique, you are too nice to put your time critique this ^W^
I will try to edit it the third time.
