The first planet I made after I went on a Mass Effect 2 binge in the beginning of 2012 and I wanted to draw comics of the game with realistic space elements.
ME2 ended up being one of the worst video games I have played (I have my own tastes and expectations, so hush up), but I enjoyed creating space scenes because of it so I continued on for a little bit.
The process of these types of creations is enjoyable and relaxing so I may do more in the future.
