This is a very nice piece of work and lovely sample of how you've designed someone else's character in a energetic and captive style. The design overall is good and you certainly seem to understand the body language of character well, the way she flocks with such energy whilst having an air of cuteness within her certainly works well and makes her an appealing person to see. What it also does is show that you know anatomy well and can not only present with with a strong understanding, but also with vigourous energy to help create the setting. Overall, the design is good but a point to make is how the arm and hand on the right look very out of balance with one another? The way it looks makes for the wrist to appear broken since it doesn't appear in connection to the arm, this might be the approach to shading you've taken which has created this look and something to think about in the future.
I think that her expression is really adorable... Just cute Also, her pose has a great style and her anatomy is really good realized... Her clothes and the accessories are a good complement for her and give a better appearance ^-^ The detail is impressive, the coloring have a nice effect and the shading give a cool aspect
