Originally they not supposed to be related, but there are some similarities. I would like to think that this is the same system, but the gas giant planets are slightly different. This one have a ring and the one in "water moon" does not have one.
One ticket for First Class with Landing Rights and Dessication Life Insurance, please. I like the deep blues of the sky with scant atmosphere. Just one thing: the combination of shadows and the lit/unlit pattern on the ringed giant feels weird, as if it doesn't correspond. But I like everything anyway, as usual.
