But here's the point (yeah, I plan on making points periodically in this Instructable, prepare yourself) it's hard to tell who's who when the lights are out. So when creating a character, you have to be aware of shapes so your creations don't end up looking like a bunch of little clones (as cool and sci-fi as that might sound). Think of it this way, if all your characters were silhouettes, would a person be able to tell them apart? If you answered yes to this question, good job, you can now close this Instructable and continue surfing the Web for cute cat pictures. JUST KIDDING, you are now legally obligated to finish reading, it's in the contract, small print, you must have missed it, don't bother going back to look, you're just wasting your time, it's really small print.
SO ANYWAY, if you said no, this is the Instructable for you; and even if you are reading this thinking it isn't, well JUST SIT AND KEEP READING, because I'll now explain why it IS. Ahem--there are no rules of creating a character. I can give you suggestions, you can Google it and read other people's suggestions, but that's all they are, suggestions. It all comes down to you to decide what works for you and what doesn't, but the more information you have in your arsenal of how-to-make-a-character-ology, the better chances you have of not creating bad characters. Or at least think of it this way, by the end of this Instrucable, you won't be any stupider, right? (It's up in the air at this point)
To help you along, I will also make a character with you during this time. It's almost like we're friends, eh?
