Her arms are over blended. Almost looks like her arm is cut off. Coloring needs a lot of work, it's boring and unappealing. Try not to have two different colors clash so hard. Goes from green to purple unsmoothly.
I actually disagree because of the fact that there is the slight change in color where the arm cuts off it seems as if she is reaching into the background. I like this a bit but the purple is out of place. Good job overall tho
