Bigger, and to my opinion, better.

Took about half an hour to render on my laptop, which, for the crap specs, is quite impressive.

Rendered in Vray/3DS Max.

PS

The full, 1920x1280 version available upon request.

You can also get a background like this, personalized to your liking, for the small price of anywhere between 2-10 bucks, whatever you want to pay. :B
