I like your overall color scheme. The cool colors with the red really make it pop.
The only problem I really have with this is her body. The arm on the left is way too big on top and as it goes down to the forearm it becomes way too skinny. Also the shoulders are too skinny and need more structure.
My suggestion is to look at pictures of real people when you draw. Even when you're doing an anime style. It'll help the picture really stand out and look natural.
Keep on drawing!
