Asura from the xbox 360 game "Asura's Wrath" ......I just started out with animated px art which is why the animation isn't THAT smooth. Actually I wanted to animate all the clothes but animating fabrics is a real pain in the ass
Some hue-shifting would really help this. The animation is great though. There is a fair bit of banding here and there though on his chest. His legs and waist are a bit too static but that's a bit of a nitpick.
Generally just by being very, very cautious with your pixel clusters. It's time consuming yes, but the end result generally looks much better because of it. (I myself have a tendency to do over-AA banding, been trying to break that habit actually) Staircase banding though is definitely the one ou want to focus on avoiding.
