Well done for taking on a project like this. It is a difficult task.
There are a lot of problems with th figure I am sorry to say. it seems you have concentrated on the musculature a bit too much, at the expense of the silhouette. It is important when you are modelling to keep "stepping back" and looking at the whole
Also to my eye it appear that the volumes of the muscles have been drawn over the surface of a figure. try observing how the muscles themselves interact, i.e. how they attach to the bones and how they go under and over each other.
Thanks for taking the time to reply
Yeah, I think I got carried away with the muscles
I think next, I will rework at a lower level and concentrate on the form and muscle flow, possibly making him a bit more natural (not so musclebound)
