I did some searches and found the artist who did the interiors and some of the covers (but not the cover you linked to) here on DA. His name is DaneRot on here. He's a pretty good artist, and the X-Files stuff wasn't bad by any means, but it does have that look of being overly photo referenced for Mulder and Scully. Which probably was insisted on by either the licensing people at Fox (or whoever owns the copyright, maybe Chris Carter) or the DC editor on the book.
Nothing wrong with that, but I like there to be more artistic freedom, especially on licensed properties. Because then you can bring something fresh and new, to something safe and established. A good example of this is the new "Ghostbusters" ongoing over at IDW. The art by Dan Schoening perfectly fits the tone of the GBs and is something we haven't seen done on previous GB books.
I think a company like IDW is a better fit for licensed property like X-Files, than DC is. They do a great job with all their licensed books. But I'm not sure who owns the comic rights to it anymore if anyone.
He is good at it, though, and it doesn't seem un-natural like some I have seen. But it looks like he only did it for the Mulder and Scully characters and not other characters on the pages I saw. But he is a good artist overall.
