This I wont waste my time on, sorry.
as for your build, rather unsurprisingly, it's shit.
Here you go, assuming you wanted to build a viable two-hander. Your build is such a mess I cant really figure out what exactly you wanted to achieve- an all rounder? Hybrid? Hybrids are for gimps. About the only place a hybrid might shine is a tournament and that's if you got a god tier one, which you could have built into a more useful specialist bro in the first place.
Anyways, try this:

depending on your recruit, you might want to substitute gifted & recover with perks more suited for your intent. Mace build for example wouldnt need recover& reach advantage, but would benefit more from backstabber & Fa instead , because when you need that mace to hit, you really really need it, while with hammer aoe spam its more forgiving and safe to stack RA. Lonewolf makes no sense on your build either, you wouldn't want this guy separated from the group. LW is for A) greataxe builds with naturally high (35 + without gifted) mdef and godly stamina so that they can roundswing twice. Considering they also need a very respectable resolve (so that they dont panic when surrounded) and cant benefit from banner much, this is one of the hardest builds to pull off. Or B) god tier duelists & fencers that want to run all across the battlefield to reach the squishies. as your bros level up, you'll find you have less need to do that.
I honestly dont know how to explain headhunter there, provided you know that greataxe head & body hit doesnt play a role in proccing headhunter. If on the other hand you wanted to opt for one handed axe's bonus head damage, then you'd want duelist as well, which you didnt take.
Same goes for fearsome, fearsome is for massive aoe spam units (Swodlancers, Warscythers, Gunners, rarely dedicated zweihanders), your guy doesnt look like he has the stamina for it in heavy armor, and will be outright gibbed by any ranged unit because you also didnt take nimble. One or the other is the difference between survival and bitch-wailing. The above-mentioned LW greataxe build would want fearsome, esp with respectable resolve of 70, but its a bitch to fit in, unless you run some mods that allow, say a perk per 5 veteran lvl or so. Then yeah, it will shine.
Crippling strike & Executioner combo is just a trap. You get marginal returns on offense in return of severely debilitating your defensive potential. And if you really want to have one, take exec, because with axes, maces and hammers, you'll already injure pretty much everything, sometimes even unholds. Two builds that benefit from Crippling Strikes are Reap spammers and dedicated shamshir duelists because with gash at 75 % you'll start injuring pretty much everything with minimal effort (yes, even lindwurms).
That's it at the first glance. Good luck, no thanks needed, just stop moaning and try to actually enjoy & learn the game.
