Nice to see you back
Hair: I think you were doing much better with your hair before. It had more highlights and stranding, so you should work on returning to that.You might want to shave down a bit of the hair since it seems a bit large for the head, unless you were going that way?
Rose: Nice touch

The shaping in particular is what you should focus on.
Dress: Nice job on the curves of your dress! One small thing need tweaking and that is the left hand side of the dress. It curves up faster than the other side, so you'll want to do more of the gradual fall. The beginning of your folds are looking nice, you just want to bring them out further. Right now you aren't seeing the other colours of your palette for the shading so remember to use them throughout, not just for a fold.
Shoes: I always find shoes on big footed bases really difficult. Next time, might I suggest shaving the feet down a bit? Its a bit advanced, but I personally find it easier to make the shoe rather than trying to make it fit the doll.
