Need Help Photoshop-Colouring This Floor Art

I was bored at work and found some scratches on the floor tiles that looked like a woman's face, neckline and bikini top! So naturally I penciled in the rest of the body and named it after a colleague that it resembled. Then out of nowhere she walks in! But she saw the funny side and loved it.

So I was hoping one of you amazing colourers could maybe spare a minute or two to slap some colour on these squiggles and make it come to LIFE!! Hehe. That'd be pretty swell, cheers peeps. You'll find copies of it via this link; including what said girl looks like IRL. (She doesn't mind )

A paint brush effect, ink, black & wite, charcoal, even a colouring pencil type shading over. Anything at all would be much appreciated. Thanks.

You might need a better pic to go off of.

Any chance you can get a stright above pic?

The first two shots are indeed rather challenging angles to work from. The graffiti was quickly removed though, for obvious reasons (keeping my job), so there’s no way of returning to the piece to snap straight shots. Is that perspective really difficult then? Here is a bigger image if it helps.
