Couple things for me,. 

Simplicity, not having to hit 3 or more links/thumbs to get to where you want to go. I've seen photography sites where you see a thumb you want to view, 6 pages later you can see it full size.

I know sites cost money to maintain, but nothing makes me close a window faster than when you click on a link or the "Play" button, and it loads an advert window before it loads what you want. I usually let it go the 1st time it happens when I visit a site, next time I leave.

Have to agree with Radlafx, no audio. 

I like photo sites that have a few links to the sites the artist visits themselves.

Good luck setting it up mate, can't wait to see your site.
