Quite a few of the shots in this section
Pixus are a little bit like the style you like. Done neither like Dragan, Dave Hill [http://www.davehillphoto.com/] or some HDR. I was just improvising with Photoshop many years ago and came up with this look, but all those pics were shot with a low res P+S camera [2.1M!], but if applied on a high res image would probably look a bit like the other techniques.
Just play around with PS, don't do things 'correctly' and see what happens.
Best way to learn, don't just copy someone's else's signature style.
