you're missing this cat shoulder blades. have a look at thisref pic (credit https://monikazagrobelna.com/2019/07/24/sketchbook-original-how-to-draw-cats/ ) - especially the second one from the bottom, left side.
I have been working on this cat for printing for some time and I just cant get the anatomy forms right, especially the front legs. This is my first time creature sculpting. I wish to get some feedback here on how it could be improved.
