Its the sprite in the first post, right?
Okay, first your shading technique is very messy making the sprite not clear at all. To me, it looks like a bird with backward claws, and wings. o.O
You have to define its anatomy, give it some muscle structure.
Your palette needs major work, I'm not even sure there is a proper palette in there.
Don't limit yourself to one color, add related colors that work together to make it stand out.
