Request for Shading Help

[makeroflight]

Hey, I've been working on a pixel art of an Adrian Helmet look-alike though modified a tad, and after finishing some quick shading I realised I have no clue how to shade this very well, if anyone could help me that would be awesome.

It does not help, sorry. I was hoping for something more shipbucket style of shading, maybe like psilanders work.
