nice start
You’re doing well sticking with the reference it seems, but there are a few areas that it looks like you could adjust:
-looks like the ribcage might be slightly short, which is causing the breasts to seem high and the shoulder joint to seem too thin. something in that area seems a bit off anyway.
-hands might be a little small (this is extremely easy to do when making female models – its a fine line between too small and mannish ;))
-ankle bones are too low – they looked more correct on the first post, perhaps you inadvertently moved them
-the pectorals, traps, delts, and sternomastoid all seem a bit too pronounced, giving a male feel
-the slope of the back moves forward too quickly – the ref’s back arch is a sharper angle than the C shape you have, this causes the bottom of her ribcage and waist to seem thin in a not-enough-room-for-organs kind of way. Also causes her bottom to feel like it goes all the way up to the midpoint of her back.
- The head isn’t looking very feminine or attractive to me, but this is quite subjective. I’d reduce the size of her chin and jaw, make her lips wider, make her eyes bigger, move the features as a whole downward slightly, shrink the forehead, and soften features overall.
Anyway, most of these things are small adjustments, and possibly not correct, Just me nitpicking a bit. Again I think you’ve got a great start here
