Hi Raven,
Was looking through and I have a couple of suggestions with your anatomy. The abs on the front view are a little thin. If you look at your figure paint overs below your skeletons, the abs kind of go from the middle of one pectoral muscle to the middle of the next. Also your Teres minor, major and infraspinitus on the back don't have enough room (the back is the most difficult part I had loads of trouble with getting those right).
I found when I was doing mine using a reference as well as marks videos made a huge difference, especially on the other perspectives,
Other than that looks like your making great progress - keep it up =)
