Think I need some serious help with this one, having a nightmare trying to draw Sarah. This is the best I've got so far, did a quick CG sketch to make it stand out.

Already spotted the eye on the left needs to be dropped a bit. It's meant to be a summer shirt/top but think it looks more like a nightie now

How can I make her look more girly? Boobs need to "stand out" more I think.
