You see, personal stuff is.. well, personal =\ I'm not the sharing type of person.. (sorry for tautology)
While fan art is an entertaining type, so I feel free to share my amusement with a game/story/characters. And I need a story behind the drawing, so it's kind of easier to tell a story in a picture, based on smth. Like 'long story short'. You can depict/include some tiny details, but people will see where it leads.
