Well - guys what do you think - let me know. I was looking in a book I have that has classic greek sculpture in it and tried something similar. There is something with the rib cage that doesn’t quite look right though…
i would go back to the anatomy books mate. ok starting from the neck look at how the visable tendons of the neck curve, if you turn your head looking over your sholder you can feel the tendons streching from behind your ear all the way to the center of the clavical. (sorry for the spelling throughout this hehehe) the collar bone needs to be smaller. less pronounced until it reaches the sholders (deltoids) were it breaks away leaving a gap for the clavical. the best way to find your way around these areas is to touch yourself… yeah anyway. pecks like you have there are going to have striations (almost wrinkles were the skin strains against the movement of the muscles. check out arnie for that one, as he was not as the lardy govner he is now.) as for the ribs you currently have female proportions for your ribcage. as a rule the female ribcage is around the same size as the hips. the masculin ribcage is much bigger. try bulking it out a bit at the sides, enhance his lats a bit over the side of the ribcage also. down to the sixpack he needs more random factors. look at how he is posed compress the his left hand side and expand the right. with muscle movment its best to use artistic licence and exaggurate. finally the pelvic muscle needs to almost over lap that final section of the sixpack look at in-vitro poses of the chest and pelvic regions. oh and how the pecks attach to the deltoids. hope this has been of some help buddy! good luck!
Thanks - I got back into working on that torso finally and here is what I came up with per a few of your instructions lol. I think it looks better - what do you think?
I also got into a tutorial about matcaps and took a turn tweaking one out here. Then I dirtied it up very slightly with some poly painting.
Looks a lot better for sure - try to use more obvious materials when modeling and getting critiques, because high contrast and cool mats hide flaws a little 
I’ll leave the real critique to better men, but I will say the ribs are wrong, look up “skeleton” on google image 
Keep at it, great work!
