It's a really nice work but there are a couple of things that draw me back for giving more points to the piece. Just my opinion and feedback, hoping to help you with these words.
It's a pity that moldline on the "stick" of the axe, as it is close to the face it draws a lot of attention ;(
Compare the upper right picture with the bigger one on the left... the blue part of the base is very bright and it draws a lot of attention, as it mimics the skin colour also... I won't paint it with that bright colour, maybe just leave a dot and the white lines to indicate the frontal arch?
