It looks neat, you was specially attentive with little details, the barbed wire and the shape of the horns.
I´m also fond of characters with exclusive or peculiar weapons, like the one you did.
The scale helps to clarify his size, i really tought it was human-sized until i saw it.
His armor looks nice, but it seems uneffective for protection, leaving all the vital areas unguarded, i would have added some metal bracers so he at least could block enemy weapons with his arms, but maybe thats just me.
Im european and i always liked our armor style, thick and covering all vitals.
Its pretty good overall, you should be proud.
