Well before we even start on a body, let's work on that face. It's terribly bland and generic, nothing about this character is memorable or striking, it's generic FF7 Cloud #513234.
Here some examples of more dynamic character faces that make for a more pleasing and unique character
See how these characters (both pixelart and traditional drawings) have a unique and memorable presence? Try to build something like that, something that will really strike the player of your game and make them remember it. Hell it'll even make it pop out and be more appealing to players, I would love to play a game starring that chicken man, he just looks like he'd have an interesting story. While your character again seems generic and presumably so is his story (now it could be totally unique but if this is the character whose my first insight into his world, his world doesn't look all that creative to me). Try drawing him on paper, experiment with his design and constantly try new ones and modify them from parts you like of the others so that you have one unique and finalized design that you can then translate to pixels.
Also your colours lack contrast and even have kind of a plastic presence. Not to mention the sprite at normal zoom is actually difficult to read.
