I love this last one. She looks less flat and rectangular, especially in the torso than in your previous work. I can definitely see improvement. For detailed anatomy fixes, JJJorgie pretty much just covered everything. The only thing I have to add is that the feet look very small compared to the figure, and the arms have a certain noodle-like quality. There is a defined joint there, so they should be bent at the elbow, not curved. There is a lot of definition around the legs that I have not seen previously, which is good. I really love the dress design; it's interesting to look at and it makes me want to know more about the character and why she's wearing it. Character development and facial expressions develop along with technique, so it's great to see these details coming out in your work. Something fun to do when you need a break from hardcore anatomy practice is just to draw lots of faces with different expressions. Angry, sad, embarrassed, etc. Its fun to do, and is important to your work.
