Did the comic fan get tired of Alex Ross ?

I think that might be an ad for the video game Bubble Bobble. But that ad appeared in so many different comics that if that's what it is, it wouldn't impossible to tell which comics it is.

ETA: here's the ad I think it is: 

I can't speak for everyone, but I did.   When Kingdom Come came out.. it was amazingly different and just knocked my socks off.

As I saw more and more of his work though, I realized that his art is very static... good for a poster, but he's not a great story teller.. once you've seem him do everyone in an iconic pose, I feel like that covers it.

I don't really agree with that assessment; but it's subjective. I think his work was more dynamic with things that were less iconic, like Astro City and Project Super Powers. Ith his DC and Marvel projects, he is limited, somewhat, by existing models and being tru to history and the established characters. With the others, he got to be more creative. I really like his penciled sketches for Astro City and would have loved to see him do a whole issue with pencil art, rather than painted. There is more subtlety to the pencil work, due to nature of the tool and it is a bit harder to capture that with paint, though he does a pretty good job, in most cases.

I don't think there is any evidence to support the idea that fans grew tired of the work. I think it is more of the case that he became a pricey artist and is used more sparingly, for greater impact and more for specialty projects like limited edition lithographs and books, while he chooses to work more for companies like Dynamite, where he has less (presumed) interference. Not to mention other commissions, outside the comic book world. By this point, it feels like he has earned enough FU money to be his own master and do what he wants to.

You also have to remember, he is in his 50s and has no need to prove himself by taking on a lot of projects. He's worked in comics for nearly 35 years. Most creators do their largest body of work between their 20 and 40s and then settle down into a pace that is comfortable for them, depending on their income and aspirations.

Alex Ross is the regular cover artist for several Marvel books each month (FF. Doc Strange at least, usually others as well) and he regularly does series of variants that not only sell well but retain demand on the secondary market (most recently the Timeless series of Heroes and Villains). His exhibits at SDCC and NYCC regularly draw sell out crowds and move lots of merch, so if anything I'd say he is as popular and as in demand as he has been through most of his career.

Full Circle sold well, and supposedly he has signed a contract to do another such project (not sure if it will be FF or something else).

What gives you the impression that fans are tired of him?

Aside from what others have said, I see no evidence of fans becoming tired of Ross. In addition to Ross being one of the few true living icons in the comic book industry, he's still creating much for several publishers. While its subjective about what is considered the best of Ross' work, he's been so consistent and still actively in demand in a manner many top comic artists of the past did not share. Moreover, unlike the majority of comic artists who saw their abilities diminish as they aged, Ross has not suffered the same fate. That's remarkable, and likely one of the many reasons he's still in demand, as he's not in the "He used to be great, but now..." category.
