I remember when I first started trying to draw the female form back in high school. I was drawing anime-inspired neko animal girl characters at the time, and I used to always draw their shoulders too broad. That in turn would cause me to draw their rib cages too big so that the size of the rib cage would match the overly large shoulders, and then I would end up giving them really large breasts to that the breast size would correspond to the overly large rib cage size. It was a mess. This chain reaction of compensating for one anatomical mistake caused people who looked at my artwork to accuse me of liking to draw girls with breasts the size of bowling balls, but honestly, that really wasn't the case! (I swear!) It was because I was unintentionally giving my ladies linebacker shoulders, and everything else turned out like it did because I could never get my ladies' shoulders drawn right.
It took a lot of practice and a little help from some art instruction books before I started drawing my ladies to where they really started to look right. My favorite art instruction book for learning how to draw the female form was actually
How to Draw Manga: Getting Started by Graphic-Sha. The book is out of print now, but you can still buy it new or used from Amazon.com here:

There are a lot of furry artists out there that like to think that they are way too "cool" to use art instruction books, but on occasion I have found some of them to be genuinely helpful, and keep several good ones on my book shelves so that I can refer to them if need be. They can sometimes give you tips, techniques, and pointers that you may have otherwise never have thought of, and at the very least the art in them can be inspiring. So don't be afraid to consult books, and I hope that my suggestion helps!
