I'm a programmer, so this could be called "programmer art"

I haven't done pixel art in a while, and I wanted to see if I could learn to animate a sprite by myself. Since I'm still learning, I kept the actual character as simple as possible, and instead of focussing on the detailing (which will be my next topic of study), I tried to focus more on animating his movements, his eyes, and some effects.

Colors used are full black, full white, red (rgb 255,0,0) and transparency.
