OK, try this. Under STYLES in the Code Editor there's a file calle nav.less. Open it and at or about line 60 (just before /* Nav */) you'll find the following code snippet:
img {
overflow: hidden;
max-width: 40px;
max-height: 20px;
The figures in bold are the ones you need to change (yours will probably be different to those shown). Try increasing the width to say, 250px and the height to 150px. Don't change anything else! Save and go back your editor. You should be able to drag the logo to a larger size via the lower-right corner. You may have to play around with the drag size and/or with these figures if you want an even larger logo.
Three things to bear in mind: First, if your uploaded logo is small (in px and bytes) it will rapidly lose image quality when you expand it. You may have to upload a higher resolution logo if that's the case. Ideally your uploaded logo should be the same size as it displays. PNG files are often better for large logos, IME, but a good quality .jpg is OK. Second, your theme isn't best suited for a large logo because your logo/nav section is always visible when scrolling, so the expanded upper space may impinge on the page contents. If so, you may need to add a spacer element at the top of your webpage content to compensate for this. Third, larger logos only really work on larger monitors such as desktops and laptops. Responsive themes (like yours) will usually shrink the logo for mobile size screens in favour of displaying the page content.
Hope this helps, Gary
