Pixel Nezu

For your very first pixel art this is fantastically done! The first thing that captured me was that it looks very professional- you knew your character very well, and knew how they would look before you drew them.
I really like the attention to detail you presented in their fur, you made every single fluffy mass of fur pop out by coloring it light as you did.
The only thing I could critique you on is the shading transitions, while a sharp transition like what you used on the majority of the fluffy chest and tail works well for long or shaggy hair- in the shorter smooth belly and leg fur, mixing the transitional colors together by checkering them will smooth out the shades, creating a less choppy shadow.

All else I can say is great job on your first pixel doll! I hope you continue to make more in the future- Congrats!
