Leslie,

This is your painting and you can do anything you would like! In fact you need to change things that don't work.

So yes, of course, add more hair. You can change the dress to have a smaller or larger collar, or one with a different shape, or one without the blue plaid, or that is just the same color as the dress. Or have no collar at all. There's no reason to include the little design on the front of the dress unless you want to because you feel it contributes something to the design. And while you're at it, you might as well change the background to suit your likes, unless you like it as it is.

Good luck.
