I believe this was art for a novelization of G-Saviour, but I really love his artwork here for G Saviour as well. Will probably post some more art from this book below just because I really like a lot of his art lol.
Various illustrations, the first is from something called Monster7 which I can find absolutely no info about (he seems to have done a lot of illustrations for novels, whether jacket or other supplemental ones), the second is for Ariel, which might be more well known because while it's a novel it got an OVA adaptation and moderoid also did kits of the giant mecha woman depicted there. And then of course, we have some other fun ones, one for a Sunrise book of some sort, and the other for a Super Robot Wars Comic Anthology.
I was wondering about this, so I dug in, and I found it! Monster 7 is a novel by sci-fi writer Kenichi Okamoto that was published in 1999. That illustration is the cover art.
The book blurb doesn't give much detail, but it sounds like the titular Monster 7 is a group of furry heroes - the names of the other characters ("Nezumi", "Balto IV", etc.) makes it sound like it's probably an entirely furry cast.
