Deer Armor

Looks pretty sweet! I like how they're all in the same pose- it makes it much easier to compare all of the individual entities within the picture to one another as far as their size and appearance goes. Although one could also argue that it makes it harder to imagine them interacting since they're only in one position.
The costumes look pretty sweet. The peacekeeper outfit reminds me of Hunger Games- though admittedly that may simply be because it's called a "peace keeper." It also vaguely resembles a storm trooper kind of vibe.
The second one is cool, though it seems a bit odd that you chose to make the biggest one the lowest rank. Normally the taller, prouder ones are associated with higher rank.
The last one looks kind of elvish in style. Kind of rogue-ish. Overall I think it works- though it does beg a lot of questions; like how did they make these outfits, and what is on the back of the last one's leg in the image without his outfit?
