I require assistance!

[Zesiul]

So I'm working on a piece, something nice and detailed that would stick right in the front of my portfolio. While a lot of if I consider done, it seems to be just a couples of hours away from completion. I wound up seeing something that isn't quite right. Now I can't exactly put my finger on what that is, but something feels off, specifically the girl perhaps her dress? I can't tell. Maybe you can?

I am dying for some words of advice, even a paint over. What am I missing here, I can't see it. I'm hoping you spot it instantly.
