I'm usually not the one to push for mature, most of the time I feel it's over used. However, here a warning might be good though. The blood is realistic enough but mostly the guy in the foreground is so obviously torn apart.
Aside from that, I always like the organic feel to your images and again it's present here. There is a feel of fire and brimstone to it all. I can almost feel the ground shake beneath the guardian. The weapons are brutish and larger than life, the weapons of bad tempered gods. Epic and scary.
