Robot Avatar :: Pixel Art Detail

I like it, and the fire looks good on my opinion =)

its very nice, but the fire not so good.

neat character but falls short in many places - the movement is jerky and cheap. make him float up and down smoother rather than "bop" and "jump" up and down abruptly. detail and shading doesn't read well. simplify him. far arm is out of place, both hands at the exact same angle to POV. brain water tank doesn't look enclosed.

I like the robot's design, but I'd suggest maybe dropping the solid black lineart. Plus, is the red brain-thing supposed to be inside or outside the tank? It'd make more sense if it were inside, but it looks quite the opposite on your piece.

Maybe making the animation a little slower and more fluid would help. It looks quite 'nervous' right now.
