I've been following Tosh through g.e for years, and I'm glad to see him move to bigger things, though I'm not even entirely sure now if he wasn't doing greater things even back then under a different alias. The way Shokugeki presents itself is a perfect match for tosh.
Hisasi has been working on character design for some anime media. I think I've seen him work on a recent anime.
Actually, I saw this one manga that looked really solid. Very unique art-style with obviously big western influences. But there was this one scene where the character designs were so good for the girls that I thought that this guy has to have done this professionally before. And he has, but most of his hobby pages have been wiped clean and you can only find the remnants of them through g.e or sadpanda. The manga is Keyman if you're interested.
I've found a few other artists delving in more mainstream styles, like Inomaru and Distance. Those can be found on manga reading website, and I'll just plug in kissmanga cause they have multipage and that's always nice. And I don't think they even care about licensed shit..
EDIT: "under a different alias"
