This is great. Very clean lined. I love the way you did the girl's eyes, those are perfect, they look exactly like her, and it looks like she's looking right out of the picture at me.
I really wish they'd stayed with the idea of the Victorian Clara being the Doctor's Companion for Series 7. This picture makes me realize that that would have made her sort of a "Mary Poppins" type governess to the children (imagine their reactions to being taken to a space amusement park and allowed to jump in no gravity, and having to keep it all secret because no one would believe them) which I believe would have added wonderful layers to Clara's characterization.
I never knew her name. soufflé Girl. Oswin. It was her. It was soufflé Girl again. Something's going on. Something impossible. Something... Right, you two stay here. Stay right here. Don't move an inch,Clara! Oswin! Oswald! Watch me run
