ok little confused i know bitmap graphic are not pixel art i can tell the differents and i can tell what pixel art is because i am useing small canvas. i am not try to relicae a bitmap graphic i am just try to make a character in sence.

Sorry I am just home grown pixel artist I visually got what wanted out of the three and my to eyes they were done but I been sprite probably for a year make assets for game. I have never had anyone on my uni course how was better than me at pixel art. so kind just going at my own pace.

You don't have to. However a small number of used colors is a kind of tradition and a sign of good pixel art. Take the time to read this document, this is an excellent tutorial that explains the basics of pixel graphics:

In particular, the section "Why not all digital art is pixel art". Look, I'm not pushing you, but hey: you submitted three works and none wasn't published. A good occasion to think, analyze your mistakes and start learning. Good luck!
