Hmm, I think gaseous planet would make more sense as the closest planet. Based on how accretion and gravity function, it would be improbably improbable for a gas planet to form as a moon, or for a terrestrial planet to have enough mass to actually capture a gas planet, since gas planets have only been recorded to dwarf rocky planets in size. It's just a small logical oversight, however. The whole painting remains very lively an intense.
hahah no problem, at least it isn't some nebula miraculously holding a planet in orbit. That's the most common thing I see, I don't even bother pointing it out. Cx
Anyway great job
