Page 12 - Armor - when you figure/show the armor section of the character sheet, it is not listing the penalty for wearing reinforced armor. Now, most items Mark's character is wearing doesn't have a penalty, but his Bracers and Greaves do, and that penalty needs to be applied.
Also, you need to decide what type of Helm he is wearing. Yes, he has a Helm made of reinforced leather, but is it a Skullcap, Pot Helm, or Full Helm. That choice will affect the "Called Shot" AR (what you have listed on the character sheet appears to be a Skullcap, which still means that the Called Shot AR is incorrect). And don't forget that Pot & Full Helms give minuses to Perception and pluses to Saves vs. Stuns
And if I might make a suggestion...
I would drop one or two ranks from Axes & Hammers and put them in his other Favored Skills, such as Riding and/or Survival. It is obvious that the Warhammer is his best weapon, so play up on that.
Thus, he has Warhammer using Clubs skill, his Hand Axes using the Axes & Hammer skill (and not quit as good with it), and his thrown as they currently are. In fact, if you only drop 1 ranks from Axes & Hammers (putting it in Riding), then his AB for Hand Axe will be the same for both melee and thrown...
But, overall, it is looking pretty good!!
