That's OK with me, if you're taking a bit of artistic license
It's just that i see a lot of people doing that, and I have my suspicions that most don't realize it's impossible.
IMO there is no problem with realism and art mixing together (many of the best space artists -Bonestell, Garlick, Bergeron, Dixon to name a few- are very realistic).... to me there is nothing wrong with including a planet and nebula in the same image as long as the planet is realistically lit by a star (which doesn't have to be on screen either)
Anyway I apologize if my rant came off as negative or anything like that
just had to get that off my chest, keep up the great work
