I just looked at your sheet as well and uhh monkey grip doesnt work the way you think it does.
It allows you to wield a larger version of a weapon, not a weapon of one handedness higher. You couldn't wield a great club. You can wield a large warhammer, or a large club i suppose, but not a great club. Also there is an error on your sheet, wielding a Tower shield gives you a -2 penalty to hit which you dont note.
