Change the site to English, start an affiliate program so other people promote your site too, change your payment processor to something well known in the industry (CCBill) and you probably want to change that design too. If you can afford it, maybe go with NATS right from the start.
I think glamour style is fine, but IMHO skinny girls just don't fit the cliche of Oktoberfest. Don't get me wrong - Anetta Keys (I've spotted her a couple times on your site) is a fine girl, but I just can't imagine her carrying 6 Maß of beer...
Feel free to hit me up if you need anything. I'm from Austria, so I'm kinda in your neighborhood.
