Here are some links to his stuff.

It looks like the page where most of his work resides is broken now.
As an artist, Gouly is not really that very great. I do not want to be that offesive, but drawing the "manga" style is totally overused with the artists of my country. It is starting to get on my nerves, kids immitating the art style of another culture and calling it their own style. It all is starting to look the same.
