She looks sad :( I hope the day got better for her and everyone at the party. I like the simple checkered background, gives more focus to the oc. :)

Everything looks great except her face is bothering me. I would pull her jaw down and adjust the distance between her facial features.

Maybe you can call her Nameless in a different language?
Like Sennoma in Esperonto. Or maybe just Clare? Anyways, its up to you.
(Love the details on her dress btw)

Your shading, line variation and style are amazing! Easily one of the best I've seen today :D
