It looks nicer but there are a few issues with it. The biggest issue is the styling applied to the html and body. Those tags are not meant to be styled in that way. Having the subreddit windowed in the body the way it is makes it look like it's not even apart of reddit. It adds empty white space to the page for no reason. To correct it remove the following stylings.

html {
    background: #ffffff;
    padding: 0px 100px;
    min-width: 980px;
}
body {
    background: #fff;
    box-shadow: 0 0 16px #000;
    margin: 0 auto;
    margin-top: 20px;
}

The next is that the only link in the navbar that underlines when you hover is the one that says Chaturbates. Here's how you can make the rest underline on hover too.

.tabmenu li a:hover {
    text-decoration: underline;
}

Another way you could make the navbar look better is remove the list item padding and put the padding on the actual link, then have it change the background color for the link. That would make it so that when you hover the link it highlights that part of the navbar making it clear that it's a clickable.
