LOVE the rain doll; that animation is great! I'd suggest editing their expressions so they seem sad to be rained out, though. It would also be good if you good layer it so that the rain falls behind the dolls too; atm, it looks a little bit like you just slapped it on top with a script or something.
The ocean fairy seems a bit squished; I'm not sure I would have used such a small bottom half for the length/size of her top half. If she had shorter arms and a smaller head, it might have worked more. But the background and frame are great, and it was very creative to use the jellies in that manner.
Not too much to say about the punks; I see dolls like that all the time, so there is nothing super new and exciting to comment on. They look nice
You're absolutely right; your dollmaking has improved by leaps and bounds! Glad you listened to our critiques; keep it up, and you'll keep getting better.
