How much description do readers typically want for the POV character? Does the amount of description ever increase or decrease immersion? Would many readers rather picture their own idea of the POV character based on the reaction of other characters in the story? Or perhaps type descriptions (cute, pretty, handsome, plain, homely, ugly, etc) rather than specific descriptions (blue eyes, brown hair, crooked teeth, sharp features, a wart on the chin, snub nose, etc)?
Also, how important is it to know 'your' name if it doesn't come up naturally in dialogue?
