The lips are fine,specially when you have the costume. There is a little bit red in the cape and in the belt as I can see, so it matches the lips. (Not sure if it is a belt lol) Make sure to upload some pictures if you are going to use this as a halloween costume or anything else!
Looks nice altho it's not my style One question tho, did you use foundation? I think it would look better if you would make your skin smooth and a little blush =) Your pretty!
