Texhnolyze, Wolf's Rain Recommendations
Similar atmosphere of dying world and hopelessness. They both are dark and sad seinens.
Similar atmosphere. Both have a female main character, who has special abilities. Both have have many male characters that are fighting (more or less) for a female main character.
Both stories tell us about survival in a post-apocalyptic world. Similar animation style and dystopian atmosphere. Both are serious and gloomy. Also, lead characters wander a lot.
both animes have slow moments allowing you to think about what is really going on
also both have same concept and similar atmosphere
Texhnolyze is an extremely niche anime, but I believe Wolf's Rain shares some similar vital points and might appeal to the Texhnolyze audience to a certain degree. At least watching Wolf's Rain really reminded me of Texhnolyze and I felt similar feelings watching them.

In short, you can get a feeling of desolation while watching both shows. They are set in universes with desolated worlds by either war, resource shortage, and exclusion of some parties. The characters are kind of similar
