Here's the thing - doing a model sheet for your characters is like eating your vegetables as a kid. You know they're allegedly apparently important, because your parents keep hounding you to eat your vegetables. It's only when you gain a little maturity that you realise how beneficial vegetables are for your body. And then a little later, you realise you like eating vegetables. Model sheets have been like that for me. I'm only just starting to recognise how beneficial they are.
