Made a couple of variations of the knight sprite (just the idle and hit, as I use them for my game). They are a "robotic armor" variation and a "demon armor" variation.

Wow, this looks great, I think I may revamp my current game's sprites with these, if you don't mind, here's the current game:

Will probably update the sprites this week, although I'm also working on a simpler attack method, so it might take a bit longer.
