Hello, me and some friends are starting the devolop of a game and i am doing the pixel art work, i need some feedback from skilled pixel artists!

Here the best body templates that i made since now, i started to learn pixel art all by zero and by my own.
Our game gonna be a survival style, and i need some advices, like wich size of characters, tiles and stuff like that!( If possible)

But now im working hard on the main character of the game and i need some feedback
