Issues with Site Identity – need to make the logo larger

Hello there! I'm working on the http://www.uptownworksnyc.com (which is still on Under Construction mode). I'm having issues setting the site identity with the logo image I have on file. The size is 1335 × 210 pixel wide but no matter what size I've uploaded, it always displays less than half of that on the page. We have the High Responsive Pro format. Please help. Thanks!
