you nailed it! Looks convincing The left one looks matured than the other.Good luck

still looks like a child to me..try adding more wrinkles around the eyes, not dramatic old lady wrinkles, but some wrinkles to show adult skin

still doesn't look older. Just looks like a pointier chin. Head proportions need to change or the body size in the older image.

Certainly not bad, I do think she has grown up features in the face but maybe some points to improve.
For a grown up she has huge front teeth, if you can make them some smaller (or perhaps close her mouth more, then they'd be better in proportion with her face.
Her chin, go back to he original chin and remove some from the (little bit of) double chin from the girl. Try not to make the edges too blurry, the way she has her head, you'd see a more sharp contour around the chin. Lastly is her body. If you see your original pic, the head is higher, the way you put the head makes it look like she misses a neck and instead it's put straight on the shoulders. I'd put her face more on the place from the original photo and if needed make her hair longer to cover the original hair or just blend the yong girl's har with the older hair. Good luck!

Very nice! I only think that, because of the angle of the body, her head looks a little big. Maybe enlarging the shoulders a little more could solve the problem. GL!

Nice work, like the gentle change.and believable
