A reference remake of my sentinel character, Seishou.
A little information about them:
Sentinels are shape-shifting spirits that patrol deserted villages and roads in search of human souls. Because of their unnatural substance, they feed off these souls in order to maintain their physical forms, which typically resemble reptile-like creatures. Their name literally means "watcher."

Common Sentinels:
-Do not have wings
-Have distinct color patterns
-Horns and spikes are very common
-Patrol small areas, and will not approach groups of humans
-Sneaky and stick together, usually in pairs

Rare Sentinels:
-May have wings or feathers present
-Markings may change or alter depending on mood
-Have a wider area to patrol
-Often challenge their prey head on, rather than using elusive tactics
-Very confrontational, and will challenge a group of humans
-Travel solo
