That is some detailed pixel art! I like the design and the fact it has a pen for a hand. I like the thin, intertwined body as well. I'm not so sure about the yellow-green combo with the shading, and the right shoulder is just black, which is weird, since it shouldn't be that dark and there's only a couple other places like that. It seems too inconsistent. I also can't tell what the black hand is. Is it made of ink? Why is it shaped like that? Is it smaller pens dipped in ink? Or just long nails for no reason?
Overall, it's detailed and a cool design, but there's some shading and color issues.
