That's pretty nice, the shading and that suit is well done.
However there are some jaggies and some pixels that have a low contrast between each other. If you want to improve, there are many tutorials such as this one in the "tutorials" section of this great website, that cover the basics of pixelart.
Pixelart is pretty hard for beginners (IMHO) but as time passes, skills develop, and the results improve.
