Your modeling is improving, it does look good, just noticed a few things.
First of all, the area I marked with blue has some stretching that personally I don't like, I'd suggest taking the edge loop that I marked in blue and rotating it down a bit to smooth it out, and on that note I think you should add some better deltoid definition since he would now have some troubles with the movement of his arms.
The eyes also seem to have some issues, they seem really quite square, and you've got some off looking topology on the head area but I think that's because he's wearing a mask (?).
Also the wrist-transition from the arms to the hands seems really bloated for some reason which obviously can't be right, and I don't necessarily mean bloated as in too big, but bloated as in the outer edges seem to be spread out a bit too much.
His thumb seems to have some strange angle to it as well, but I really can't tell from the angles you posted.
But it looks good, keep it up.
EDIT: About the shoulder and deltoid thing, he seems to be wearing some sort of armor, so that may explain some things, but I suggest just changing some of the geometry just for the sake of the topology. Although if you want to keep it go ahead, it doesn't look that odd.
