battle character design in Your undertale AUs

Hey, can anyone give me some small advice on UT pixel art? Rn I am doing sans and so far I FINALLY got the mouth right, got the eyes and lil' nub of a nose. I only went with a cloak on my last sprite because I couldn't draw a jacket lol. Edit: see article

Somebody ones told me to make Papyrus Sprite taller and not only him, so I did it.
Sprite by me.

Red Underfell Sans and Gaster Blaster Sprites by me.

Not short anymore. Idk... what have I made ? lol
Made by me.

These are the current sprites for the game I'm coding called:

GameTale: LoaiSayah Fight

This post has the head animation sprites, leg sprite, torso sprite and what it looks like together

Little dodging animation I made

Before I go to sleep I'll leave you this

Best sprite I've ever seen.
