Looks really good for 4 colors! Keep it up!

I use large color palletes for my drawings but I think I should try atleast 5 or 6 colors for next time. I kinda went too far with this one.

Inklings are like that, I was using the amiibo as reference and I noticed that while I was drawing it, the head is pretty big and they're body is small. Also, I don't see anything wrong with the teeth but anyway thanks for the criticism, it helps me a lot.
