Same cockpit placement... same landing gear placement... same cockpit escape hatch placement... same vernier rocket placement... similar length... same modular fuselage... even similar angle of view for the spacecraft.
If you can't see the similarities and the utterly obvious influences... I strongly recommend watching the actual show.
stuff that amounts to "if it has vaguely the same shape and is set in space, then it MUST be fanart, even if it wasn't intended that way"
Eeeeh... I really don't see the similarities you point at. Sure, it's a long spaceship with a cockpit and four landing legs, and it's landing on the moon, but that's far from saying it's the same ship. Wishful thinking and fanboy goggles are fine, but it's not something you should base tags on.
Oh, and even if this WAS Space: 1999, it would not have a place in the East meets West pool. Which you would know, if you'd glanced at the pool description. Or the name of the pool... Hell, it wouldn't really belong in Animified either. Also, learn what a Dutch angle is.
