Hey!
first off…good job on teh torso.i can see that the muscles groups are present and are in proportion 
The problem which i see with this model…is tat it doesnt quite follow the curvature of the “human” torso…but fear not…only a few movements will hopefuly change that.
I think u should slim down the lower part of teh abdominal muscles…decrease the waistline…hes looking “fat” and that doesnt follow any “gesture”…its extremely difficult to do that in zbrush with negligible reference…u should have a “V” shape present in the flow…
another thing i see is taht u SHOULD span out the back wings…the wings are big enough here to be seen from the front…so make them more spanned out
Also…(i just checked my anatomy)…the external upper obliques shouldnt be going that far back…that space in the back is taken up by the lattisimus dorsi…the muscle which joins in the back wing and folows right around the dies into the oblques…main point…reduce obliques and add maas to the lattisimus dorsi…i wish i could show u what i mean…but do a search on bodybuilders…as they habe the anatomy ur going for
plus…i think u should decrease his waist line :P…hes looking obese…but i think i hve said that alreasdy…
well…this is what i think…pretty small things tho…
CHECK UR ANATOMY!!! all along the way
just a few tweaks here and there…tehe model itself is very good
update us asap! :)
