It's looking good but i think you should try reaching a higher LOD on your HP model, this way your work in the LP is going to be much easier.
At this POV i can see you've working on the clothes detail, sort of fabric seams, but you're lacking of detail on the border, at the end of the suit's sleeves you have a big seam where it turns inside.
Another thing, you're spending too much tri's on the mouth area, you should try collapsing this edges to the half, the normal map is going to do all that work for you. This way you reduce the number of tris in this area, no edges needed, just the normal map.
You've achieved a great detail in the hand (as for the base normal map).
Besides this, the shirt's neck is lacking of tri's.
It's the same for the suit's chest, you can't emulate this detail only with normal map, you have to do all the tri's work and then extract it into a normal map. This way is going to look much more realistic.
The same applies to the rest of the suit. Maybe it's time to spend more time doing fabric detail, the holes in the suit where the buttons go, etc...
The same goes for the shoes.
You can achieve a lot of detail with the normal map pass in one shot just working with the HP in the right way.
I use Max. And I used polygon modeling for juste about everything. The arms and legs where done withe a bit of Cloth simulations. And the middle parte of the suit was done very simply in polygons, then modified with a bit of cloth, and finaly some zbrush just to make the folds going to the belly.
