I think it looks pretty good overall, but the eyes and the large ears (this might just be me, but they look bigger than normal) make it look kind of alien, unless that's what you were going for.
In my experience, it's been helpful to try and focus on one or two problem areas at a time. If there's a little bit off about a lot of things then it can be hard to figure out what's wrong, because it can't be narrowed down. I'll go from bottom to top.
The butt cheeks are too high up. They don't feel attached to and controlling muscles in the legs, more just like domes implanted on top of an otherwise flat ass. This would be helped significantly by bringing the butt down.
The torso is too long. It's not impossible for humans to have torsos that long but it's highly unusual, so it looks off.
The breasts look super compacted. For their apparent volume, too much of the weight is being held high and to the side. So lose some of the volume or move some of it from the sides and top to the bottom-front, or both.
The collarbone is pretty low, super shallow, and the musculature doesn't make as much sense as it should. It's important, when drawing or modeling bones and muscles, to think about what their purpose in the body is. They don't just exist to exist. Neck muscles link up between the neck bones, collarbones and jawbone in specific ways for specific functions, so it can be helpful to imagine those functions while sculpting them.
The head is the most difficult to make solid recommendations on because faces vary so much, but her ears were way outside of the standard size, and her mouth is extremely small, the nose is on the large end, the eyes are much larger and much more bulbous than average, with much deeper pits than usual. So in the GIF below I averaged out her features somewhat to help make her look a little more normal.
I hope this helps!
Thanks to you both!, Indeed her ears and eyes are too big I guess in trying to get the right shape I just didn't think too much about the size and sabrina. that's so much more helpful information than I hoped for I don't know how to thank you taking your time to even do a visual demostration. I did look at reference from time to time while sculpting but seeing the same thing for hours can make it difficult to see what's wrong, indeed your version looks much better. I think I'll be better if I start from scratch with all of your advice in mind but I feel much more condfident now.
