I'm guessing here that 'Chucks' are the shoes she's wearing ?
They are a nice strong colour to photograph - the only issue is that they get a little lost in the business of the picture. You have a mass of vertical and horizontal lines in this shot, as well as very ligh and very dark areas, all of which lead the eye away from the shoes.
Perhas if you could have gone for a simpler shot, with a less cluttered background ? maybe even get the model to bring her feet up onto the table and rest her chin on her knees so that she is a more compact shape, and the shoes are sideways onto the camera, so we can get to see them in all their glorious pinkness ? :- )
Here. I'll help you towards the brown. If this is a serious shot, it is too dark, your shot center is about the knees (which are OOF), the legs are at a weird angle, the POV is too low (looking up at the underside of the picnic table), and there is way too much in the shot besides the chucks.
