Nice one, I think he looks good! The outline around the outside of the abs looks a little extreme to me, given that there is almost no definition in between the individual muscles there, i think you could do well to smooth that section out a bit. Also, I'd push the sword design some - maybe its just from Advent Children but I'd rather this guy had something a little less Buster Sword-y. Very nice start, I would not abandon this - the legs, face and shoulders are all very strong I think.
