Ok now you changed that pic. Thats better:
But still you have been quite inspred by RT.
I just took a quick look at the html.
<html>
<head>
<meta http-equiv=content-type content="text/html; charset=UTF-8" />
<meta name="robots" content="noindex, nofollow">
<title>404 - Sorry, the page you requested could not be found.</title>
<link rel="stylesheet" href="/errors/error.css" type="text/css" />
</head>
<body>
<div class="auroraframe">
<div class="bg error-404">
<span>Sorry, the page you requested could not be found.</span>
</div>
<div class="help-links">
<div class="title">Here's some links that should help you get back on track:</div>
<ul class="links">
<li><a href="/">Home</a></li>
<li><a href="#">Contact Us</a></li>
<li><a href="/help">Help</a></li>
<li><a href="#">Forum</a></li>
<li><a href="#">Documentation</a></li>
<li><a href="#">Hosting</a></li>
<li><a href="#">Tutorials</a></li>
</ul>
</div>

but thats OK for me and you may have noticed that I put the word "stolen" into " " ...
You can obviously do a lot of cool things Aurprathemes and I have no doubt that you could do your own really orignal-"Aurorathemes"-design easily ....
