@The-Wizard-of-Zaar: Thanks. I'm glad you like them. ^^

Not all my sci-fi pictures are in the same setting, despite looking like they might belong together due to, well, being drawn in my style. This is based on the game 'Lancer', which is about big Mech battles. You can play it as an heroic campaign with larger than life villains or as a grim and dark "war is hell" one (with anything in between). The tone and mood of the setting is often decided before the game begins, but I think Lancer works significantly better with the former. The other submission you're referring was made for a "Those Dark Places" game, which, as the name suggest, is indeed geared towards slow-burning, creeping horror and is clearly inspired by movie "Alien".
