Trouble changing fonts

Instead of putting your font-family in the reset section, try changing it lower down, where you have:

body, input, textarea {
	color: #373737;
	font: 15px "Helvetica Neue", Helvetica, Arial, sans-serif;
	font-weight: 300;
	line-height: 1.625;
}

Also, in the reset, you have this:

font-family: font-family: ‘Walter Turncoat’;

That;s not quite right.

Finally, and I should have pointed this out first, you should create a child theme, otherwise, when a new update comes along, you will loose your changes.
