I love this guy. As with all your other pieces, it seems to tell a story through simple details like the Eye of Horus tattoo on his hand and the military uniform, and the way that you did the decapitation seems to sort of emphasize his less-than-human nature. Creepy as hell and really made a strong impression on me, and I actually ended up being inspired by it to write a short story. ([link]) Admittedly it's only tangentially related at this point, but I thought I should let you know.
This reminds me o the book "War against war" or "Krieg dem kriegen" in it's original language. I'm sure you've heard of it, and if you haven't, You should! it's obviously quite shocking but I think it would be inspiring for you maybe?
