This story was made during the tail end of Enki Bilal’s early period, as his art style starts to move away from the heavy influence of Moebius. The transition is very obvious on this page, which starts with more traditional Moebius elements that are surplanted by stuff that looks more like Bilal’s middle period work. I love the first panel in particular, where the floor is actually some kind of viewscreen that he can use to watch ships.
