I took Wilex's advice and changed the torso area up; focusing on the areas he mentioned (small of back, hips, ribs and so fourth).
I admit, I kind of made anatomy up in that area my first time through instead of looking at references.
Now he should hopefully be somewhat anatomically correct (for a demon creature).
The one thing I realize that I did not do is bring the lats down and around the ribs as much as I should.
Therefore, his lats are extremely small, but I did this to maintain the characters tapered silhouette.
Unless anyone has any other important things to point out that I missed, its on to the low poly build.
Here are the changes I made, and I threw in a close up of the hands for the hell of it.
