It happens quite often where I see people posting lots of pictures of their "new OCs" because they were just drawing and they created something that doesn't look like their other character, or it's made to look somewhat like something they saw before and wanted to recreate for themselves, or whatever reason.
First off; I've been there. I used to do the same thing. Then when I grew in character development I recycled some of the old ideas into stronger characters with more dept.
What I don't think a lot of people realize is that you don't have to call that drawing a character, as it really isn't a character until it has depth. Until the figure in your picture has a soul and a story that's really all they are. A picture. A drawing.
I've learned that not every thing I draw needs to be turned into a character, but I could use some of those left over designs if I ever wanted something to start from.
There's so much more to a character than what they look like. What age are they in this picture? What did they look like when they were 4? Why do they look like that now? What's their favorite food? When did they lose their virginity? To who? What are their goals and dreams? Did they ever stand up to the bully that picked on them in grade school? WHat did they say? How do they hold themselves; Tall or timid? These are just a few of the things to consider when you're building a character with depth. Rather, these are some of the things to consider BEFORE you design their outward appearance.
This has been an ill-composed rant/something about character creation.
