Camilla

Well, to start it off the hairstyle of Camilla is a good choice for battling.
Then, here is where I am going to help you. The hands might need some more development. I suggest maybe changing the color scheme or even the design of the battle armor and the facial expression and body language of Camilla since I feel like that it should more serious or more to her personality. I also recommend changing the headband to just a clip since the headband looks annoying( sorry).
When doing the shading try to figure out where the light is coming from (behind or in front of her etc.) I also recommend putting a better background that you created instead of one that is already created.
I think I am done here.
PS- Sorry making this critique like criticism. Hopefully this will help you. <img src="e.deviantart.net/emoticons/w/w…" width="15" height="15" alt="" data-embed-type="emoticon" data-embed-id="387" title=" (Wink)"/>
