My Pixel Characters

[Zatsuki]

This is my first time posting here. I would like to improve my skills so I am making free pixel characters as a hobby. If I am not allowed to post my pixel characters, please tell me so I could delete all of it. 
I am hoping to make sprite sheets too but, it depends on the time I have. :3

Each picture has minor changes and I would like to know which is better. That way, I could continue on making a sprite sheet.
