Well, this is a cover picture of a story/comic. I'm not sure how fast can I do this, we will see.
There are 2 plantes which comes very close periodically. But the upcoming event is different, the 2 planets come so close each other the atmosphere can mix. Using this event, my character will try to fly through the other planet to give important informations there. Yes, this 2 planet is both have inhabitants, but different in species/cultural/enviromental/technological. Because and event in the past.
