well there is alot of work to be done anatomically. I'm doing a paintover right now.
The biggest problem is that your biceps are way to big in comparison to the other parts of the lower arm, shoulder and even pectorals
look at this picture of blanka, see how the biceps are in comparison?
The stomach has no definition to it, and the muscles under the pect's are a bit long, they dont stretch past the nipple.
The shape of the bicep is also off a bit
The legs look like noodles, you need to study some anatomy picture to know exactly how muscles fit together, theres alot to know.
The neck's also a big big but I'm sure you knew that, as small heads make the muscular bodies look real big.
Overall it just looks like your guestimating about muscular anatomy. I used to do the same thing, alot.
I would definately suggest looking at some body builder pictures, or better yet... here.

look around there, at the definition of the legs and the shape of the bicep and how it inches and curves it's way around the arm. Also the deltoids size in relation to the pects, and how the pects stretch if the arm position is up.
Just go through every image and the check your model from the same view and move some verts around.
Good luck and happy modelling.
