Too much or too little contrast?

[ExNavyDoc]

Got rejected for cropping and contrast. Fixed the cropping, and bumped the contrast and saturation a little. Got rejected on the second go round for contrast.

Which way should I take the contrast? Up or down? Or are the highlights maybe too blown to make a difference?

Thanks!
