Two things that bug me.
1) The Ram Skull axe, there are nails in the base that are pointing upwards towards the hands/arms of the wielder. I would remove those.
2) The three skull axe, the first notch in the axe handle looks more like a serious crack, any impact on that considerable axe head would probably snap it in half quite easily.
You keep tilting towards the left side, weapons are crafted in heights.
