Couldn't you just had put this in your last thread instead of this one?
And there are still anatomy issues, as before, the arms are too short, the abs are too huge and far apart, the legs are WAY too tiny and have barely any detail at all etc.
And adding that alpha all over his body is just overkill, it's way to repeated in my opinion.
Also that being zBrush, it probably won't have that of a great topology, obviously you could retopologys (Can't spell that correctly) the model in a separate modeling software.
EDIT : I suggest starting to model in a non sculpting software (Zbrush is still a sculpting software to me) and learning on from there, and when you have the knowledge to make a good basemesh with good edgeflow take it into zbrush and make the normal/bump map from there.
