Sculpting - Human - Male arm

After human male torso, I kept continuing sculpting other parts of body, this time, a male arm. Also, I'm trying to sculpt each of these parts as realistic as possible with references I have.

First, this sculpting was so bad that I had to start up a new one, but still, a good sprint to get to know how the arm will turn out.

 Rather than putting details on hand, I was just trying to focus on detailing and getting the scale of the arm right.
