This is from Borderline (Point du rupture), a grim, violent, Skynet-esque, dystopian, post-apoc work he did with fellow countryman Carlos Trillo.
I'm re-reading it now, and frankly, I don't remember how well I liked it before. That's usually not a tremendously encouraging sign, but... let's see how things shake out this time. For others of the post-apoc genre, I still maintain my master list at the evil empire, for those curious.
Anyway, I love Risso's art. More here:

EDIT:
Just finished the four-tome series (link added above).
Now I don't think there's any question that this one's patterned after Miller's Sin City, altho yes, the setting is quite different. I'd say what immediately stands out is the difference in focus.
For example, while Miller was a bit 'loosy-goosy' in following various characters across his nightmarish version of 'Vegas,' he chose to dedicate long story-arcs to each chapter & book. Meanwhile, Trillo & Risso focused their entire time on a specific, local clash between ruling factions and their minions, parsed in to short stories. (and yes, they were often part of an arc)
TBH-- altho I'm not nearly a fan of Frank Miller as I used to be (in his own words, he loves to aim 'way over the top,' while I'm more 'ordinary people' inclined), I don't think there's any question that Sin City has the better focus, dramatics, and storyline.
Now this is maybe foolish, or maybe appropriate to our reality, but one thing I really appreciate is when there's something of a background, or at least basic research, in to the relevant science of a story. Instead, it seems to me that the logic and science in Borderline are mostly there just to serve the story. That's completely common of course, but...
OTOH, the art really is phenomenal, the core ideas are out of classic pulp-SF, and my impression of American audiences is that they won't mind the violence too much. In short, I suspect this is perhaps one of those series which sort of stylistically divides The Americas from Europe, if I may make so bold a statement, hehe.
