Here's this sketch of my creature:

hope you guys like it, if you want I can draw early stages

Info:
The Ostreetian is a race of one-legged birds which are pretty near being sentient, they move by hopping and they attack with their leg which is quite heavy and powerful (it's used to attack enemies by jumping high then kicking them), they use no guns since they have no arms/hands to build them but they use their small (not usable for flying) wings which have a really hard and sharp structure to attack and cut their prey. Their third eye gives them a good vision but they have no ears and realy purely on ground vibration detected by their leg. (can be easily attacked by flying creatures unless they see them in time in which case they can defend themselves with their wings).
