Not so sure about the right leg of the cat but I couldn't do any better. I particularly like the one of the girl the end of her nose if a bit shaded but other than that it looks like a drawing for a girl in a disney movie which is good by the way really good. Plus she's hot. Just saying.
I like your style! the proportions are just fine 😊 maybe the first stripes of the cat look odd, I mean I think they should be on top as they get closer to the head and the tail on full view would look better too (or does it have a short tail?)
