@LauraA I love this!!! They have a slight Arthur Rackham vibe, which I really like.
I might agree with @Mimi-Simon on just two expressions: the one where Hansel turns to Gretel outside the candy house and MAYBE the witch’s expression when she is swooping in. Since they’re larger, or more close-up, I think I expect to see just a touch more detail as compared to the faces that are further away or smaller. For the witch specifically, maybe I’d expect to see more delicate linework or wrinkles, but honestly, it’s just the one expression of Hansel that I might hone a little more. It looks a little more 2-d compared to the others. I think all the other expressions and gestures work really well.
