im pretty sure i found that pixel artist you were looking for! well one of them at least
http://schinkensp i cker.deviantart.com/gallery/ (without the spaces, for some reason it's censored idk why)
here is the complete sheet, he has some of those in his gallery, but not every single one so it's probably with other artists too, and here is the same sheet which gives credit to all those other artists/people that contributed, at the bottom.
baww too late
