dont take it as offense, I know that links gloves are pretty long, but your arms that you modelled in relation to his body are too long, and thats partially because his hands are too long.
If you look at that picture you posted, look where his fingertips fall, mid thigh...
Now rotate the arm you modelled at the shoulder, they fall from what I can tell at the knee.
thats all I was saying, you dont have to do anything that I said. I was just trying to help you out.
the muscle detail is just scaling of edgeloops. You have enough detail I can see to do some scaling/moving and you will be good anatomically.
Ive studied the human anatomy for several years and thought I could might shed some light on things, but if you dont like it I'm sorry and you dont have to take my advice.
