Answer 1

What hand?

I can see part of it, but not enough to notice if it is different than anyone elses hands.

Answer 2

I can barely see his hand. . .it looks kinda big, though.  

Years of punching bags (and heads) do make hands thicken and broaden, but this guy looks too young for that.  I once shook hands with Floyd Patterson.  Honestly, his hand felt like dry, tough leather. . . . and his fingers were the width of smoked sausages.  

I'll guess the pic is of a boxer or mma fighter.
