While Tetsuya Nomura has more or less taken over the art scene since Final Fantasy VII was made back in the mid-90's, Amano is still involved and is still the series' "title logo designer", among other things. With every new FF title that comes out, there's usually at least half-a-dozen new illustrations of his to go with it.
Amano is by far one of my favorite artists of all time. I fell in love with his work when I was just a kid and as I've gotten older, I've only grown more and more impressed by it. While he has lots of amazing stuff that has nothing to do with Final Fantasy, the series has no doubt helped him spread his wings as an artist. Well, enough of me talking about it...have a look for yourself:
