Sh_dz8 I'm not in the brain mode to do much work on story crit right now, but I think someone else has a thread going around for that so that might be helpful on that side of things.
For her design, I'm not sure what time period her story takes place in, but using the context of some other outfits and the characters In your heroes folder to assume that this is modern if not past that. But essentially I'd play around with different kinds of activewear since right now it feels somewhat simple for someone with so much money and I think you can pull out more personality from her with specific fashion choices/accessories. For instance, her bow is very "traditional" in a sense, if you wanted to look up compound bows that might be fun. You can even play around with her hair more, a more pulled-back look might be good for her active lifestyle. And lastly, I think her color palate could be de-saturated, I know working with traditional media can be limiting at times but you can get a good range of color even with a cheap pack of colored pencils. On that note even playing around with a new palate entirely could be interesting, what's throwing it off right now is that the colors used don't belong to any of the same groups, the yellow is pure yellow, the brown is in the red family and the purple is more blue-leaning. So try to look into some color theory in general and I'll help fix that.
