If you start with character, you probably will end up with good drawings.
As you become acquainted with a character you are creating, you add parts of yourself that are pertinent to that character.
An idea has no worth at all without believable characters to implement it; a plot without characters is like a tennis court without players. Daffy Duck is to a Buck Rogers story what John McEnroe was to tennis. Personality. That is the key, the drum, the fife. Forget the plot.
Each character represented a trait that resides in me.
