Stuff's gotta get guarded. That's just the way of the world.
I sketched these while noodling around on a project that's, for the time being, on the back burner. The shape of each guard is loosely based on a letter of the alphabet, A-E. That was my main constraint, then I tried to see what kind of variation I could inject into them. They're all pretty European, which I'll change if I return to the project.
For now, enjoy!
