Of course you shouldn't use a grid, but to see if you're doing the proportions right, it's important to draw the same size as your reference (it's what Dan always sais btw ;) ). It's nothing like using a grid, it's just to make it easier - otherwise you're bound to screw up the proportions, it's natural. I guess the brain isn't able to calculate them correctly or something. I don't know, just try it, all of a sudden your mistakes will become obvious. And it's no cheating - unlike the overlay technique ;)
